It needs to run to the 04 Multi-step direction to simplify the detection of the Page 58 Chapter 5 Parameters VFD-M-D Series lifetime will be shorter and it can be damaged due to higher temperature, failing insulation and unstable torque output.

For instance, if Pr. The deceleration time has to be set accordingly. Frequency Frequency output output This parameter must be equal to or less than Mid-Point Frequency Pr. Output freq. The setting of the Motor no-load current will affect the slip compensation. It can limit the maximum output frequency. After faults such as O. The signal when it is in open When Pr. When Pr. The speeds frequencies are determined by Pr. When using with door control system Pr. The signal for the door close limit is received before Pr.

Incorrect door close limit: a. The signal for the door open limit is received before Pr. Refer to Pr. Low-Voltage Indication Operation Mode Active when operation command is controlled by external terminal. Under such circumstances, DC Braking can be used to hold the load in position before setting it in motion. Page Chapter 5 Parameters VFD-M-D Series O pera tion continues after fault clear, O pera ti on continues after fault clear, speed sear ch starts w ith the minim um freque ncy speed search star ts with th e Master F requency reference value After removing the cause of the fault, use the reset command to reset the drive.

AC drive address is 01H. When reading Parameters parameter by command code 03H, only one parameter can be read at one time. RS BUS Once a fault is detected, the corresponding protective functions will be activated. The following faults are displayed as shown on the AC motor drive digital keypad display. The four most recent faults can be read from the digital keypad or communication.

Make sure that the ventilation holes are not obstructed. Overheating Remove any foreign objects from the Heat sink temperature too high heatsinks and check for possible dirty heat sink fins. Torque boost too high: Decrease the torque compensation setting in Pr.

Load may have changed suddenly. Can acceleration Can deceleration time be made longer? Reduce load or increase Or power cut, Restart after reset including momentary power loss Check if there is any malfunction Change defective component component or disconnection and check connection Is load too large Reduce load If cooling fan functions normally It may cause the misoperation of control circuit and even damage the AC motor drive.

Of course, that is a solution to increase the noise tolerance of AC motor drive. The solutions are as follows. High Harmonic at Power Side If there is high harmonic at power side during running, the improved methods are: 1. Preventive maintenance is required to operate this AC motor drive in its optimal condition, and to ensure a long life. It is recommended to have a check-up of the AC motor drive performed by a qualified technician.

Daily Inspection: Basic check-up items to detect if there were any abnormalities during operation are: Whether the motors are operating as expected. Applicable Motor Output kW Max. Page Appendix B Accessories B. Please contact your nearest Delta representative for use of special resistors.

Page B. We assure that it can comply with following rules when AC motor drive and EMI filter are installed and Inductance mH Fundamental continuous Amps Wire Size Wiring Method Please wind each wire 4 times around the core. The reactor must be put at inverter output as close as possible. If the capacity of AC motor drive is too large, it cannot offer complete protection to the motor and motor maybe damaged. Page C.
