parameters are automatically scaled by the command from the logic

input:

• DC injection current

• Brake release current

• Nominal motor current

Second Torque Limit

Second Torque Limit reduces the maximum motor torque when the

logic input is closed (state set to 1). Use the 2—Adjust menu to

configure the percentage of torque.

Fault Reset

Fault reset erases a saved fault and resets the drive controller if the

cause of the fault has disappeared. Two types of reset are possible:

partial or total. This is set by the rSt parameter in the 6

—Fault menu.

For a partial reset (rSt = RSP), the following faults are reset and

cleared from the display:

For a Total reset (rSt = RSG), all faults except SCF (Motor Short

Circuit) are overridden as long as the logic input assigned to Fault

Reset is closed.

• input line overvoltage • motor overload • motor overheating

• overbraking • network

communication fault

• loss of RS-485 port

communication

• motor phase loss • loss of 4–20 mA • drive overheating

• ramp not followed • external fault • overspeed

CAUTION

MOTOR OVERHEATING

• Repeated reset of the thermal state after a thermal overload can

result in thermal stress to the motor.

• When faults occur, promptly inspect the motor and driven

equipment for problems (locked shaft, mechanical overload, etc.)

before restarting. Also check the power supplied to the motor for

abnormal conditions (phase loss, phase imbalance, etc.).

Failure to follow these instructions can result in equipment

damage.
