3.1 LED Monitor, Keys and LED Indicators on the Keypad
As shown at the right, the keypad consists of a
four-digit LED monitor, six keys, and five LED
indicators.
The keypad allows you to run and stop the motor,
monitor the running status, specify the function code
data, and monitor I/O signal states, maintenance
information, and alarm information.
When using a multi-function keypad instead of a remote keypad, read the Multi-function Keypad Instruction Manual.

Unit: Hz, A, kW, r/min and m/min
Refer to Chapter 3, Section 3.3.1 "Monitoring the running status" for details.
Unit LEDs
(3 LEDs)
While the inverter is in Programming mode, the LEDs of Hz and kW light.
 Hz  A  kW

Indicators
x10 LED
Lights when the data to display exceeds 9999. When this LED lights, the "displayed
value x 10" is the actual value.
