Step 3 – Initializing parameters
To initialize the drive parameters to factory defaults, set parameter n001 = 12.
This will set the V7 to accept start/stop commands in what in termed “2-wire control”, i.e. 1
wire for a motor forward/stop 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 correctly
setting this, the V7 will protect an overloaded motor from burning out.
Read the rated current (in amps) on the motor nameplate, and enter this into parameter n036. The example
to the below shows entering a value of 1.8Amps.
