Default Relay Output Descriptions
Drive OK - When the drive is clear of all shut down faults, the Drive
OK contact is closed. The drive does not have to be enabled to be in
the drive ok state. This normally open contact is available for use in
the motion controller control stop string. The contact is closed when
there are no faults.
Enable Brake Solenoid - This output contact is used to interface to a
brake solenoid. The contact closes immediately after the drive enable
is applied. The drive will apply zero speed holding torque for a
configurable on delay time period after the drive has been enabled
(parameter 206). This assures that there is holding torque available
while the brake is being released. An additional off time delay is
provided (parameter 207). The brake contact will open after a
configurable time delay period (parameter 207) from when the drive
enable input is removed. The drive will remain enabled for the off
delay period to provide regenerative braking until the motor is at zero
speed.
High Winding Select - When bit 2 of the parameter set binary code
is set to 1 the High Winding Select contact is closed. When interfaced
to a contactor, this output is used to select the high motor winding.
This contact is closed only when the low contact output is open.
Low Winding Select - When bit 2 of the parameter set binary code is
set to 0, the Low Winding Select contact is closed. When interfaced to
a contactor this output is used to select the Low motor winding. This
contact is closed only when the High contact output is open.
