Frequency setting by external terminals
Remote setting function
When the remote function is used, the output frequency of the inverter can be compensated for
as follows:
External operation:Frequency set by RH/RM operation + external running frequency or
PU running frequency (other than multi-speed).
(When making analog input compensation, set "1" to Pr. 28
"Multi-speed input compensation selection".
When Pr. 28 is set to "0" and acceleration/deceleration is made to
reach the set frequency of the analog voltage input (terminal 2 or
terminal 4) by RH/RM, the auxiliary input by terminal 1 becomes
invalid.)
PU operation:Frequency set by RH/RM operation + PU running frequency
Frequency setting storage
The frequency setting storage function stores the remote setting frequency (frequency set by
RH/RM operation) into the memory (EEPROM). 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
affect writing.)
