RUN indicator: flashes ALARM indicator: off Setting/monitor indicators: FREF, FOUT or IOUT is lit. Data display: displays the corresponding data for the indicator that is lit. When fault has occurred, the details of the fault will be displayed. In that case, refer to user’s manual and take necessary action. Step 3 – Initializing parameters To initialize the drive parameters to factory defaults, set parameter n01 = 8. This will set the J7 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 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. Key Sequence Indicator Display example Explanation Power On Press the Mode Key repeatedly until the PRGM indicator is lit. Press the Enter Key. The data of n01 will be displayed. Use the Increment or Decrement Key to set n01 to 8. The display will flash.
Press the Enter Key so that the set value will be entered and the data display will be lit. In approximately 1s. The parameter number will be displayed.
