Chapter 4 Parameters

02.06Loss of ACI Signal (4-20mA)

Factory Setting: 0

Settings 0 Decelerate to 0Hz

1Coast to stop and display “AErr”

2Continue operation by the last frequency command

This parameter determines the behavior when ACI is lost.

When set to 1, it will display warning message “AErr” on the keypad in case of loss of ACI signal and execute the setting. When ACI signal is recovered, the warning message will stop blinking. Please press “RESET” key to clear it.

02.07Up/Down Mode

Factory Setting: 0

Settings 0 By digital keypad up/down keys mode

1Based on Accel/Decel Time acc. to Pr.01.09 to 01.12

2Constant speed (acc. to Pr. 02.08)

3Pulse input unit (acc. to Pr. 02.08)

02.08	Accel/Decel Rate of Change of UP/DOWN Operation with		Unit: 0.01
	Constant Speed
	Settings	0.01~10.00 Hz/2ms	Factory Setting: 0.01

These parameters determine the increase/decrease of the master frequency when operated via the Multi-function Inputs when Pr.04.05~Pr.04.08 are set to 10 (Up command) or 11 (Down command).

When Pr.02.07 is set to 0: increase/decrease the frequency by using UP/DOWN key. It is valid only when the AC motor drive is running.
