*
1
Momentary average deceleration torque refers to the deceleration torque from 60Hz down to 0 Hz. This may vary depending on the motor.
*
2
Parameter L3-04 should be disabled when a Braking Resistor or Braking Resistor Unit is connected.
*
3
Overload protection may be triggered at lower levels if output frequency is below 6 Hz.
*
4
Protection may not be provided under the following conditions as the motor windings are grounded internally during run:
• Low resistance to ground from the motor cable or terminal block.
• Drive already has a short-circuit when the power is turned on.
