Are external motor disconnects required between the motor and the VFD? Service disconnects at motor loads are very often used for maintenance purposes. Normally, removing a load from a VFD while operating does not pose a problem for the VFD. On the other hand, introducing a load to a VFD by closing a motor disconnect while the VFD is operational can be fatal to the VFD. When a motor is Started at full voltage, as would happen in this case, high currents are generated, usually about six times the full load amps of the motor current. The VFD would see these high currents as being well beyond its capabilities and would go into a protective trip or fail altogether. A simple solution for this condition is to interlock the VFD run permissive circuit with the service disconnects via an auxiliary contact at the service disconnect. When the disconnect is closed, a permissive run signal restarts the VFD at low voltage and frequency. * Are there power factor correction capacitors being switched or existing on the intended motor loads? Switching of power factor capacitors usually generates power disturbances in the distribution system. Many VFDs can and will be affected by this. Isolation transformers or line reactors may be required for these applications.

Question: How do I reset the drive back to factory default settings? Answer: Go to parameter A1-03 and set value 2220 for 2 wire control or 3330 for 3 wire control (Please refer to Step 6 for wiring diagram) Question: How do I adjust the time it takes the motor to speed up or slow down? Answer: Adjust the acceleration time parameter C1-01 and deceleration time C1-02. Question: How do I prevent my drive from tripping on an OV fault (overvoltage) while my motor is ramping down? Answer: Increase deceleration time parameter C1-02. Question: How do I prevent my drive from tripping on an OL1 fault (overload) while my motor is ramping down? Answer: Verify motor rated current parameter E2-01 and motor overload parameter settings L1-01 Motor overload selection, L1-02 Motor overload protection time.
DANGER: Improper wiring can and will cause bodily harm as well as damage to the equipment. When installing the system be sure to follow good wiring practices and all applicable codes. Ensure that the mounting of the various components are secure and that the environment, such as extreme dampness, poor ventilation etc. will not cause system degradation.
