Increase/decrease the Master Frequency each time an input is received or continuously when the input stays active. When both inputs are active at the same time, the Master Frequency increase/decrease is halted. Please refer to Pr.02.07, 02.08. This function is also called “motor potentiometer”.

Parameter value 12 programs one of the Multi-function Input Terminals MI3~MI6 (Pr.04.05~Pr.04.08) to increment the AC drive’s internal counter. When an input is received, the counter is incremented by 1.

When active, the counter is reset and inhibited. To enable counting the input should be OFF. Refer to Pr.03.05 and 03.06.

Parameter value 14 programs one of the Multi-function Input Terminals MI3~MI6 (Pr.04.05~Pr.04.08) to be External Fault (E.F.) inputs.

When an input ON with this setting is ON, the PID function will be disabled.

AC motor drive will stop output and the motor free run if one of these settings is enabled. If the status of terminal is changed, AC motor drive will restart from 0Hz.

When this setting is enabled, all parameters will be locked and write parameters is disabled.
