•For Single-Phase Pulse Input Signal Operation
(1) Connect the pulse input signal between the terminals PGA1 and PGA2 or between PGB1
and PGB2.
(2) The polarity of the pulse input signal should be:
+side ... PGA1 or PGB1
- side ... PGA2 or PG82
(3) Changeover of the forward and reverse operation is possible when the command mode is
valid for terminal input (parameter
