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:

• mains overvoltage • communication fault • motor overheating

• DC bus overvoltage • motor overload • serial link fault

• output phase loss • loss of 4–20 mA • drive controller overheating

• ramp not followed • external fault • overspeed

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.

Force to Local

Permits going from serial link command to local command using the

keypad display or terminal strip, depending on the setting of the LCC

parameter in the 4

—Control menu. Assigning this parameter selects a

local command when the logic input is closed (state 1).

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.
