1.7 H: Terminal Functions
148 YASKAWA ELECTRIC SIEP C710606 10A YASKAWA AC Drive - V1000 PRELIM. Programming Manual
Setting 16: Motor 2 Selection
The drive has the capability to control two motors independently. A second motor may be
selected using a multi-function digital input (H1- = 16) as shown in Figure 1.50.
Figure 1.50
Figure 1.50 Motor Selection
Motor 2 is selected when the input set for Motor 2 Selection closes. When operating motor
2,
•E3- and E4- become valid for motor control. Refer to E3: V/f Characteristics for
Motor 2 on page 119 and E4: Motor 2 Parameters on page 121 for details.
• accel/decel times set in parameters C1-05/06/07/08 are activated (Refer to C1-01 to C1-
08: Accel/Decel Times 1 to 4 on page 77 for details).
• E4-14 is used as gain for slip compensation instead of C3-01.
• E4-15 is used as gain for torque compensation instead of C4-01.
• a digital output programmed for “Motor 2 Selection” (H2-01/02/03 = 1C) will be
switched on.
Note: 1. When using 2 motors, the motor overload operation 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 a "rUn"
alarm.
Setting 18: Timer Function Input
This setting configures a digital input terminal as the input for the timer function. Refer to
b4: Delay Timers on page 58 for details.
Setting 19: PID Control Cancel
When the PID Function has been enabled by b5-01 (PID Mode Selection), it can be
indefinitely disabled by closing a digital input configured as a PID Disable (H1- = 19).
When the input is released, the drive resumes PID operation. The PID Block Diagram on
page 63 illustrates how the function works.
