They are both equally effective. They can also be used in combination. Refer to the attached technical note from a manufacturer of AC chokes and DC reactors for a detailed explanation of solutions to harmonic noise in AC drives.
Otherwise, an OH alarm cooling fin overheat may occur. Also, a minimum 1. Refer to the appropriate drives instruction manual for the mounting and clearance specifications. Answer: A blinking error message will appear EF , and the motor will decelerate to stop. Note: If both the forward and reverse commands have been shut off, then the motor will restart. See TM.

Other bounds can be set on the reference by configuring the Bias parameter, n Please refer to TM. Answer: Yes.
Capacitors are put across the AC power line to correct for lagging power factor due to inductive loads. Motors, relay coils, transformers, etc. Many times capacitors are switched on and off the line as demand changes. Unfortunately, this switching results in large voltage spikes on the power line which can damage the drives rectifier circuit.
If overvoltage faults are indicated, add dynamic braking -- this will clamp the DC bus. Possible Cause s : Digital operator cable not securely connected, digital operator defective, control board defective. Corrective Action: Disconnect all control wires from the drive.
