Field heat On
When parameter FldHeatSel (21.18) = On, the feature works as follows:
Condition
Power Up:
Start drive:
Normal stop:
Off2 while running:
* Parameter Off2 Emergency Off / Coast Stop (10.08) must be set to a valid input bit number for
this to be valid. Default value is DI-4.
** If parameter 44.04 is set below 100%, field will be at this reduced level while motor is stopped.
Field heat OnRun
When FldHeatSel (21.18) = OnRun, the feature works as follows:
Run (StartStop,
Jog1, Jog2, etc.)
Off
On
On or Off
All other conditions
* Parameter Off2 Emergency Off / Coast Stop (10.08) must be set to a valid input bit number for
this to be valid. Default value is DI-4.
** If parameter 44.04 is set below 100%, field will be at this reduced level while motor is stopped.
The Estop Input
In both modes of operation, the estop input (configured with parameter 10.09) is cleared
while the drive is off, the field will turn off. It will not turn back on again until the estop input
is again set. If estop is cleared while in motion, the motor will decelerate to a stop, the
drive will turn off, and then the field will shut off.
