2 Output Voltage PID
YASKAWA TM.A1000SW.061 Output Voltage PID A1000 Custom Software Supplement 11
„ Motor 2 Operation
Motor 2 can be selected by programming a multi-function digital input H1-0 = 16:
• When Motor 2 control method is NOT set to V/f (E3-01!= 0), and the Motor 2 input is closed, the output voltage PID,
the output current voltage compensation, and the Iq voltage compensation functions are disabled. Also all of the P1
parameters, P2 parameters, and U7 monitors are not viewable.
• When Motor 2 control method IS set to V/f (E3-01 = 0), and the Motor 2 input is closed, Parameters P1-04 & P1-06 will
be scaled to parameter E3-05 (instead of E1-05). All three functions, Output Voltage PID, Output Current Voltage
Comp and Iq Voltage Comp, will be operational.
