Control Wiring 5-21 MN765
5.5.15 Bipolar
Provides bipolar speed or torque control (torque control is only available in Vector modes). The control is operated by the
digital inputs and the command source. The opto inputs can be switches as shown in Figure 5-19 or logic signals from
another device.

Digital Output 2 +
J2-8 CLOSED allows normal control operation.
OPEN disables the control and the motor coasts to a stop.
J2-9 CLOSED to enable operation in Forward direction.
OPEN to disable Forward operation (drive will decel to a stop if a Forward reference command is still
present). Reverse operation is still possible if J2-10 is closed.
J2-10 CLOSED to enable operation in the Reverse direction.
OPEN to disable Reverse operation (drive will decel to a stop if a Reverse reference command is still
present). Forward operation is still possible if J2-9 is closed.
Note: If J2-9 and J2-10 are both opened, the drive will decel to a stop.
J2-11 CLOSED causes the motor to rotate in the forward direction until the load reaches a marker or external
switch location.
OPEN allows normal operation.
Note: Parameter P2308 sets the homing offset. The motor rotates at the speed set in P2307 until the
index pulse is detected and then at the speed set in P1001 until the offset is reached.
J2-12 CLOSED puts the control in torque command mode, Vector modes only.
OPEN puts the control in speed (velocity) command mode. Note: If a stop command is issued while in
the torque (current) mode, the control will stop but will not maintain position (zero current). This is
different than zero speed operation for the velocity mode.
J2-13 & J2-14 Select from four parameter tables as defined in Table 5-13.
J2-15 Momentary CLOSED to reset fault condition.
OPEN allows normal operation.
J2-16 Optional External Trip input (not required). If used, you must set Level 2 Drive Protect block, External Trip
to “ON”.
CLOSED allows normal operation.
OPEN causes an External Trip to be received by the control (when programmed to “ON”).
