Step 3 – Initializing parameters
To initialize the drive parameters to factory defaults, set parameter n01 = 8. This will set the J7 to

command, and 1 wire for a motor reverse/stop command.

Step 4 – Set the motor rated current
This parameter is used for the electronic thermal function for motor overload detection (OL1). By cor-
rectly setting this, the J7 will protect an overloaded motor from burning out.
Read the rated current (in amps) on the motor nameplate, and enter this into parameter n32. The
example to the below shows entering a value of 1.8Amps.
