4-6-28 Inverter Ready Signal
The inverter outputs the inverter ready signal (IRDY) when it is ready for oper-
ation (i.e. when it can receive an operational command).
4-6-29 Forward Rotation, Reverse Rotation Signals
Forward Rotation signal – The inverter continues to output the forward rota-
tion signal (FWR) while it is driving the motor for forward operation. The FWR
signal is turned off while the inverter is driving the motor for reverse operation
or stopping the motor.
Reverse Rotation signal – The inverter continues to output the forward rota-
tion signal (RVR) while it is driving the motor for reverse operation. The RVR
signal is turned off while the inverter is driving the motor for forward operation
or stopping the motor.

ready signal
ON The inverter is ready to accept the
operation command
OFF The inverter is not ready to accept
the operation command
Valid for inputs: 11, 12, AL0 - AL2
Required settings: C038, C039
Notes:
• The inverter can recognize only the operation command is given while the IRDY
signal is given out
• If the IRDY signal is not given out, check whether the input power supply voltage
(connect to the R, S, and T terminals) is within the range of specification
