The following seven steps describe the recommended minimum operations to allow the J7 to control a connected motor in typical configuration, to allow simple operation in the quickest time:

Step 1 – initial checks

1-1 Checkpoints before connecting the power supply. Check that the power supply is as of the correct voltage.

CIMR-J7AZ2@@@: Three phase 200 to 230VAC

CIMR-J7AZB@@@: Single phase 200 to 240VAC (Wire R/L1 and S/L2)

CIMR-J7AZ4@@@: Three phase 380 to 460VAC

1-2 Make sure that the motor output terminals (U/T1, V/T2, W/T3) are connected to the motor. 1-3 Ensure that the control circuit terminals and the control device are wired correctly.

1-4 Make sure that all control terminals are turned off.

1-5 Set the motor to no-load status (i.e. not connected to the mechanical system)

Step 2 – Connecting the power supply and check the display status

2-1 After conducting the checks in step-1, connect the power supply.

2-2 If the display is normal when the power is connected it will read as follows;

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.

	Key			Indicator	Display	Explanation
	Sequence				example
						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					The parameter number will be displayed.
	1s.

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 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			Indicator	Display	Explanation
	Sequence				example
						Displays the parameter number
						Use the Increment or Decrement Key until n32 is displayed.
						Press the Enter Key. The data of n32 will be displayed.
						Use the Increment or Decrement Key to set the rated motor current. The
						display will flash.
						Press the Enter Key so that the set value will be entered and the data
						display will be lit.
	In approximately1s.					The parameter number will be displayed.

Step 5 – Set the motor rated frequency

This is the maximum frequency the motor can run and allows the J7 to properly control the motor. Read the rated frequency (in Hz) on the motor nameplate, and enter this into parameters n09 and n11.

Step 6 – Set the operation command

This is the method for motor run and stop commands (i.e. how the inverter will start and stop the motor). The two basic operations are for the RUN and STOP/RESET keys on the Digital Operator, or for one of multi-function inputs through the control circuit terminals.

To set the operation command, enter the appropriate value into parameter n02:

0 = RUN and STOP/RESET keys on the Digital Operator are enabled.

1 = Multi-function inputs through the control circuit terminals.

The diagram to the below shows how to connect a switch to start/stop the motor in the forward direction in “2-wire control”. Set parameter n02=1. To enable a separate switch for reverse rotation on control terminal S2, set parameter n36=2 (this is actually the factory default setting for n36).

FWD RUN/STOP

REV RUN/STOP

Step 7 – Set the frequency reference

This is the method for selecting the source for the motor speed command. The factory default is for the potentiometer on the digital Operator (FREF adjuster), in which case no setting is required.

Frequency reference can also come from an external potentiometer, an analog output from a PLC, or up to 8 pre-programmed speeds held in the inverter and selected via the multi-function inputs.

For example, to accept frequency reference from an external potentiometer, or a 0-10V analog out from a PLC, set parameter n03=2.
