Current monitoring
You can set the reference value of current monitoring.

When power is restored after an instantaneous power failure, you can start the inverter
57 Restart coasting time
without stopping the motor (in a coasting status). When this time (Pr. 57) elapses after
power was restored, the inverter begins to restart.
When you set "9999", the inverter will not restart. Generally, you may set "0", but you
can adjust the time (0, 0.1 to 5s, 9999) according to the load magnitude.
58 Restart cushion time
When the restart coasting time (Pr. 57) elapses, the output voltage is risen gradually.
Set this cushion time (Pr. 58) (0 to 60s).
Normally, you can perform operation with the factory settings, but you can adjust them
according to the load magnitude. Pr. 58 is valid only during V/F control.
You can make remote setting of the speed when the operation panel is located away
from the control box.
0: None
Remote setting
