ACE recommends the use of a double-pole, Use a 50K ohm, 1/4 W potentiometer for speed control. Connect the counter-clockwise end of thesingle throw master power switch. The switch should be rated at a minimum of 125 VAC and 200% of potentiometer to S0, wiper to S2, and the clockwise end to S1. If the potentiometer worksmotor current. inversely of desired functionality, (i.e. to increase motor speed, you must turn the potentiometercounterclockwire), power off the drive and swap the S0 and S1 connections. See the Operation sectionMotor for alternative wiring setups.Connect the DC armature leads to terminals A1 and A2. If the motor does not spin in the desireddirection, power down the drive and reverse these connections. Regenerative BrakeShort terminals S0 and T0 to regeneratively brake the motor to zero speed. The time it takes the motorField to come a stop is dependent on load inertia, friction, and the FWD TQ and REV TQ trim pot settings.Connect the field leads to terminals F1 and F2 for a 100 VDC field. Open terminals S0 and T0 to accelerate the motor to set speed.Do not make any connections to F1 and F2 if using a permanent magnet motor. Do not use the regenerative braking for emergency stopping.LOGIC (TOP BOARD)POWER (BOTTOM BOARD)ConnectionsFUSESTOPSWITCHAC LINEVOLTAGE115 VAC50K OHMSPEED ADJUSTPOTENTIOMETERCWNOTE: DO NOT makeany connections toF1 and F2 if using apermanent magnet motor.InstallationMounting• Drive components are sensitive to electrostatic discharge. Avoid direct contact with the circuit• board. Hold the drive by the chassis only.• Protect the drive from dirt, moisture, and accidental contact.• Provide sufficient room for access to the terminal block and calibration trim pots.• Mount the drive away from heat sources. Operate the drive within the specified ambient operating• temperature range.• Prevent loose connections by avoiding excessive vibration of the drive.• Mount the drive with its board in either a horizontal or vertical plane. Six 0.19” (5 mm) wide slots• in the chassis accept #8 pan head screws. Fasten either the large base or the narrow flange of the• chassis to the subplate.WiringUse 18 - 24 AWG wire for logic wiring.Use 14 - 16 AWG wire for AC line (L1, L2) and motor (A1, A2) wiring.Shielding GuidelinesAs a general rule, ACE recommends shielding of all conductors. If it is not practical to shield powerconductors, ACE recommends shielding all logic-level leads. If shielding of logic-level leads is notpractical, the user should twist all logic leads with themselves to minimize induced noise. Refer tothe user’s manual for details on earth grounding shielded wires and filtering.FusingACE drives require an external line fuse for protection. Use fast acting fuses rated for 125 VAC orhigher and 150% of the maximum armature current. Fuse the HOT leg of the AC line.ALL DIMENSIONS IN INCHES [MILLIMETERS]DimensionsSafety Warnings• DO NOT INSTALL, REMOVE, OR REWIRE THIS EQUIPMENT WITH POWER APPLIED. Have a• qualified electrical technician install, adjust and service this equipment. Follow the National• Electrical Code and all other applicable electrical and safety codes, including the provisions of the• Occupational Safety and Health Act (OSHA), when installing equipment.• Circuit potentials are at 115 above earth ground. Avoid direct contact with the printed circuit board• or with circuit elements to prevent the risk of serious injury or fatality. Use a non-metallic• screwdriver for adjusting the calibration trim pots. Use approved personal protection equipment• and insulated tools if working on this drive with power applied.• Reduce the chance of an electrical fire, shock, or explosion by using proper grounding, over-current• protection, thermal protection, and enclosure. Follow sound maintenance procedures.• ACE strongly recommends the installation of a master power switch in the line voltage input. The• switch contacts should be rated for 125 VAC and 200% of motor nameplate current.• Removing AC line power is the only acceptable method for emergency stopping. Do not use• regenerative braking, decelerating to minimum speed, or coasting to a stop for emergency stopping.• They may not stop a drive that is malfunctioning. Removing AC line power is the only acceptable• method for emergency stopping.• Line starting and stopping (applying and removing AC line voltage) is recommended for infrequent• starting and stopping of a drive only. Regenerative braking, decelerating to minimum speed, or• coasting to a stop is recommended for frequent starts and stops. Frequent starting and stopping can• produce high torque. This may cause damage to motors.• Do not disconnect any of the motor leads from the drive unless power is removed or the drive is• disabled. Opening any one lead while the drive is running may destroy the drive.• The field output is for shunt wound motors only. Do not make any connections to F1 and F2 when• using a permanent magnet motor.• Under no circumstances should power and logic level wires be bundled together.• Be sure potentiometer tabs do no make contact with the potentiometer’s body. Grounding the• input will cause damage to the drive.READ ALL SAFETY WARNINGS BEFORE INSTALLING THIS EQUIPMENT.............................................................115 VAC ± 10%, 50/60 Hz, single phase...................................................................................................1.77 at base speed.................................................................................................................100 VDC...................................................................................................1 Amp.............................................................................................1 second.............................................................................................1 second.........................................0 to ± 10 VDC......................................................................................200K ohms..................................................................................................3% base speed........................................................................................................................50:1...........................................................................................0.5G maximum...............................................................................................0.1G maximum...................................................................................10°C - 55°C..............................................................................................................................0.6 lbsAC Line VoltageForm FactorField VoltageMaximum Field CurrentAcceleration Time RangeDeceleration Time RangeAnalog Input Voltage Range (Signal must be isolated)Input Impedance (S0 to S2)Load RegulationSpeed RangeVibration (0 - 50 Hz)(>50 Hz)Ambient Temperature RangeWeight1/8 - 1/2ArmatureHorsepowerRange5.0ContinuousArmatureCurrent (Amps)0 - 75ArmatureVoltage Range(VDC)115LineVoltage(VAC)RGH100-5ModelSpecifications |
