Baldor mn722 Bipolar Speed and Torque Mode Connections, Bipolar Mode Table Select Truth Table

If J1-16 is connected, you must set Level 2 Protection block, External Trip to “ON” to activate the opto input.

CLOSED allows normal operation.

OPEN causes an external trip to be received by the control. The control will disable and display external trip. When this occurs, the motor stop command is issued, drive operation is terminated and an external trip fault is displayed on the keypad display (also logged into the fault log).

Momentary CLOSED to reset fault condition. OPEN allows normal operation.

Bipolar Speed and Torque Mode Connections

Provides bipolar speed or torque control. Also, you may store up to four (4) complete sets of operating parameters. This is important if you wish to store and use different acceleration rates, speed commands, jog speeds or to store tuning parameter values for different motors etc. The opto inputs can be switches as shown in Figure 3-22 or logic signals from another device.

Figure 3-22 Bipolar Speed or Torque Connection Diagram

J1-8 CLOSED allows normal operation.

OPEN disables the control & motor coasts to a stop.

J1-9 CLOSED to enable operation in the Forward direction.

OPEN TO DISABLE Forward operation (drive will brake to a stop if a Forward command is still present).

Reverse operation is still possible if J1-10 is closed.

J1-10 CLOSED to enable operation in the Reverse direction.

OPEN to disable Reverse operation (drive will brake to a stop if a Reverse command is still present).

Forward operation is still possible if J1-9 is closed.

Note: If J1-9 and J1-10 are both opened, the drive will brake to a stop.

J1-11 CLOSED causes the motor to rotate in the forward direction until the load reaches a marker or external switch location.

OPEN allows normal operation.

J1-12 CLOSED puts the control in torque command mode. 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.
