Setting Operation

Caution

*1. t1 will be a shorter time of either the setup value of SV.Pr6B or elapsing time for the motor speed to fall below 30r/min.

t1 will be 0 when the motor is in stall regardless of the setup pf SV.Pr6A.

*2. For the action of dynamic brake at alarm occurrence, refer to an explanation of SV.Pr68, "Sequence at alarm ("Parameter setup" at each control mode) as well.

*3. When an alarm has been given, the homing is not completed. So, all the transistors of the current posi- tion output (P1OUT to P32OUT: CN X5 Pin 29, 30, 31, 32, 33 and 34) turn OFF (point “0”).
