To use RS-232 Communications, the optional RS-232 Interface Card is required.
a. For one to one control: Using a PC, PLC or some sort of control device to control one Inverter,
set (
Fn_100
) to (1).
b.
An ASCII CODE is used for FM100 communication.
c. (
Fn_10
) and (
Fn_11
) will be ineffective for Inverter operation and frequency control while in
the communication mode.
d.
The frequency signals Upper and Lower Limits are controlled by (
Fn_06
) (
Fn_07
) while in the
communication mode.
e.
The PC will request data from the Inverter automatically to obtain information on the
(STATUS_LED, VAC, VPN, IAC, Frequency, RPM).
f.
The Inverter will confirm the validity of the new parameters when set by the PC.
g.
Please refer to the RS-232 and RS-485 communications manual for detailed function and
protocol information.

Fault Log:
Last 3 Faults
In order to simplify any troubleshooting, the Inverter records the last three fault codes automatically
in its EEPROM memory. Press the Up & Down arrows on the Keypad to review the recorded
faults.
Sample: 1. (LV-C)
The first fault code. The latest is Low Voltage.
2. (OC-d)
Overcurrent during deceleration.
3. (- - - -)
No Fault Recorded. Only two faults occurred.
