Frequency setting by external terminals Parameter
6 - 56
Remote setting function
When using the remote setting function, following frequencies can be compensated to the fre-
quency set by RH and RM operation according to the operation mode.
During external operation (including Pr. 79 = 4):
external frequency command other than
multi-speed settings
During external operation and
PU combined operation (Pr. 79 = 3):
PU frequency command
or terminal 4 input.
During PU operation: PU frequency command
Frequency setting storage
The frequency setting storage function stores the remotely-set frequency (frequency set by RH/
RM operation) into the memory (E²PROM). When power is switched off once, then on, operation
is resumed with that output frequency value (Pr. 59 = 1).
The frequency is stored at the point when the start signal (STF or STR) turns off or every one
minute after one minute has elapsed since turn off (on) of both the RH (acceleration) and RM
(deceleration) signals. (The frequency is written if the present frequency setting compared with
the past frequency setting every one minute is different. The state of the RL signal does not af-
fect writing.)
