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 or 230 VAC 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 techniques,• 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 250 VAC and 200% of motor nameplate current.• 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.• 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.ALL DIMENSIONS IN INCHES [MILLIMETERS]Dimensions0.19 [5]A2.10 [53]0.82 [21]0.96 [24]3.64 [92]0.19 [5]1.75 [44]0.70 [18]4.30 [109]3.80 [97]IL501TH501305QIL502105TC503105CC505C502C504105RDIBIHNI TLIMITS3S2S12L1L 2A 1ACURRENTPOWE RCURRENT LIMITDECEL ACCELIR COMPMAX SPD MIN SP DMODEL DIMENSION “A” HEIGHTPWM400-2 2.50 [62]PWM400-5 3.20 [81]PWM400-10 3.90 [99]InstallationMounting• Drive components are sensitive to electrostatic discharge. Avoid direct contact with the circuit• board. Hold the drive by the chassis or heat sink 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. Eight 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.• The chassis should be earth grounded. Use a star washer beneath the head of at least one of the• mounting screws to penetrate the anodized chassis surface and to reach bare metal.Heat SinkingThe PWM400-10 requires an additional heat sink when the continuous armature current is above 5amps. Use ACE heat sink kit part number HSK-0001. Use a thermally conductive heat sink compound(such as Dow Corning 340® Heat Sink Compound) between the chassis and the heat sink surface foroptimal heat transfer.WiringUse 18 - 24 AWG wire for logic wiring. Use 14 - 16 AWG wire for AC line and motor 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. It may benecessary to earth ground the shielded cable. If noise is produced by devices other than the drive,ground the shield at the drive end. If noise is generated by the drive, ground the shield at the endaway from the drive. Do not ground both ends of the shield.FusingACE drives require an external line fuse for protection. Use fast acting fuses rated for 250 VAC orhigher and 150% of the maximum armature current. Fuse the HOT leg of the AC line when using 115VAC and both lines when using 230 VAC.MOTO RFUSE*FUSESTOPSWITCHAC LINEVOLTAGE120/240 VAC10K OH MSPEED A DJUS TPOTENTIOMETERCW* NOTE: Do not add fuse to L2unless input voltage is 230 VAC.InhibitTerminalsLine InputConnect the AC line power leads to terminals L1 and L2. ACE recommends the use of a double-pole,single-throw master power switch. The switch should be rated at a minimum of 250 VAC and 200% of motorcurrent.MotorConnect the DC armature leads to terminals A1 and A2. If the motor does not spin in the desired direction,power down the drive and reverse these connections.Speed PotentiometerUse a 10K ohm, 1/4 W potentiometer for speed control. Connect the counter-clockwise end of thepotentiometer to S1, the wiper to S2, and the clockwise end to S3. If the potentiometer works inversely ofdesired functionality, (i.e. to increase motor speed, you must turn the potentiometer counterclockwise),power off the drive and swap the S1 and S3 connections.InhibitShort the INHIBIT terminals to coast the motor to zero speed. Open the INHIBIT terminals toaccelerate the motor to set speed. Twist inhibit wires and seperate them from power-carrying wires orsources of electrical noise. Use shielded cable if the inhibit wires are longer than 18 inches (46 cm). Ifshielded cable is used, ground only one end of the shield to earth ground. Do not ground both ends ofthe shield. Do not use the inhibit for emergency stopping.ACE offers two accessory plug harnesses for connecting to the inhibit terminals; part number KTW-0001[18 in (46 cm) leads] and part number KTW-0002 [36 in (91 cm) leads].ConnectionsIL50 1TH501305QIL50 2105TC503105CC505C502C504105RDIBIHNI TLIMITS3S2S12L1L 2A 1ACURRENTPOWE RCURRENT LIMITDECEL ACCELIR COMPMAX SPD MIN SPDPOWERLOGIC |
