Outputting a Signal during Forward/Reverse Running

 How to detect information during the forward rotation of the inverter and inform the system?
Q
 How to detect information during the reverse rotation of the inverter and inform the system?
 Assigning "Forward rotation [FWR] (51)" or "Reverse rotation [RVR] (52)" to one of the output
A
terminal functions ([C021]/[C022]/[C026]) enables the inverter to output a forward/reverse
rotation signal.
 The [FWR]/[RVR] signal is not output while the voltage is being output from the inverter to the
!
motor due to DC injection braking or other reasons.
