Publication 8720MC-IN002A-EN-P — December 2002
SCANport Command Interface 4-5
Jog Request - If the drive is stopped (disabled via bit 00 of the
command word) and the jog command bit is set true (rising edge) and
there are no faults, the drive will assert the jog reference enabled state
and follow SCANport jog reference command on SCANport adapter
Input Word 2.
The drive will continue to follow the jog reference until the jog is
released. It will then regenerate to a stop.
The manual reference request, bit 11 of the SCANport Logic Command
Word, does not need to be asserted. This will automatically occur
when the jog bit 02 is set.
Fault Clear - If a drive shut down fault has occurred setting the
Drive_Err_Reset bit is required in order to reset the drive shut down
error. The fault cannot be reset unless the fault condition is removed.
Coast Stop Request - If the drive is running and the Coast Stop
Request bit is set the drive power will be removed from the motor and
it will not regenerate. Under this condition the motor will coast until
the friction of the motor and load bring it to a stop.
Refer to the tables below for SCANport I/O key logic commands.
