(F) Setting of acceleration/deceleration time and acceleration/deceleration pattern Parameters
5 - 114
The multi-speed operation function is invalid when remote setting function is selected.
Even when the remotely-set frequency is cleared by turning ON the RL (clear) signal after turning
OFF (ON) both the RH and RM signals, the inverter operates at the remotely-set frequency stored
in the last operation if power is reapplied before one minute has elapsed since turning OFF (ON)
both the RH and RM signals.
When the remotely-set frequency is cleared by turning ON the RL (clear) signal after turning OFF
(ON) both the RH and RM signals, the inverter operates at the frequency in the remotely-set fre-
quency cleared state if power is reapplied before one minute has elapsed since turning OFF (ON)
both the RH and RM signals.
E
CAUTION:
When using the remote setting function, set the maximum frequency again according to the
machine.
