Protection Design IP20 open-chassis, NEMA Type 1 enclosure (option)
* 1 Momentary average deceleration torque refers to the torque required to decelerate the motor (uncoupled to the load) from the rated motor speed down to zero in the shortest time.
* 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.
