5.7 H: Terminal Functions240 YASKAWA ELECTRIC SIEP C710616 27G YASKAWA AC Drive A1000 Technical ManualFigure 5.63 shows an operation example of Fast Stop.Figure 5.63Figure 5.63 Fast Stop SequenceNOTICE: Rapid deceleration can trigger an overvoltage fault. When faulted, the drive output shuts off, and the motor coasts. To avoidthis uncontrolled motor state and to ensure that the motor stops quickly and safely, set an appropriate Fast Stop time to C1-09.Setting 16: Motor 2 selectionThe drive has the capability to control two induction motors independently. A second motor may be selected using amulti-function digital input as shown in Figure 5.64.Note: The motor 2 selection function cannot be used when PM motor is used.Figure 5.64Figure 5.64 Motor SelectionWhen switching between motor 1 and motor 2, the parameters used to control those motors also change. Below,Table 5.37 lists the parameters that correspond to each motor.Table 5.37 Parameters for Switching Between Two MotorsNote: 1. When using 2 motors, the motor overload protection selection (oL1) set to L1-01 applies to both motor 1 and motor 2.2. It is not possible to switch between motor 1 and motor 2 during run. Doing so will trigger the “rUn” alarm.3. There is a 500 ms delay when switching during CLV control and a 200 ms delay for all other control modes. Wait for at least thesetimes after switching the motor before issuing the next Run command.4. The motor 2 selection function cannot be used when PM motor is used.If a digital output is programmed for “Motor 2 selection” (H2-01, H2-02, or H2-03 = 1C), the output is closed whenmotor 2 is selected.Setting 18: Timer function inputThis setting configures a digital input terminal as the input for the timer function. Use this setting combination with thetimer function output (H2- = 12). Refer to b4: Delay Timers on page 166 for details.Setting 19: PID disableWhen the PID function has been enabled by parameter b5-01, it can be indefinitely disabled by closing a digital input.When the input is released, the drive resumes PID operation. Also refer to PID Block Diagram on page 170.No. Setting 16 Open (Motor 1) Setting 16 Closed (Motor 2)C1-: Acceleration/Deceleration Time C1-01 to C1-04 C1-05 to C1-08C3-: Motor Slip Compensation C3-01 to C3-04 C3-21 to C3-24C4-: Motor Torque Compensation C4-01 C4-07C5-: Speed Control (ASR) C5-01 to C5-08, C5-12, C5-17, C5-18 C5-21 to C5-28, C5-32, C5-37, C5-38E1-, E3-: V/f PatternE2-, E4-: Motor Parameters E1-, E2- E3- to E4-F1- (PG Constant) F1-01 to F1-21 F1-02 to F1-04, F1-08 to F1-11, F1-14, F1-31 to F1-37Run/StopTIMEFast-StopH1- = 17Decelerates at C1-09ON ONONONOutput FrequencyMMDrive Motor 1Motor 2Motor switch input
