Verify Option Operation

„ Apply power to the drive.
„ Verify that the diagnostic LEDs on the front of the option are in their correct state.

„ Remove power from the drive and wait for the charge lamp to be completely extinguished. Wait at least five

additional minutes for the drive to be completely discharged. Measure the DC BUS voltage and verify that it is at a
safe level.

„ Install the operator keypad and all drive covers.

Initial Settings

Since the option utilizes the AC drive for many of its calculations; such as speed, please check the following parameters to

verify the correct setting.

Run/Stop and Frequency Selection

The run/stop commands and frequency reference command can originate from serial communication, the Digital Operator, the
external terminals, or the option. The origin of the run/stop command does not have to be the same as the origin for the fre-
quency reference command. Parameter b1-01 (Reference Selection) allows you to set up the origin of the
frequency reference and parameter b1-02 (Operation Method Selection) sets up the origin of the run/stop commands. When
the DeviceNet network is connected to the drive, the motor speed and the status of the drive can be monitored via DeviceNet
while controlling the drive from another source specified by parameters b1-01 and b1-02. The table shown below illustrates
the possible frequency reference and run/stop selections.

Make sure to set number of motor poles (2 ~ 39) to input and output motor speed in

RPMs on DeviceNet control and operator display.

DeviceNet indicates the motor speed unit as RPM.

o1-03 setting value is used since the option converts frequency to RPM. Initial

value is 0 for frequency reference in Hz.
