Frequency setting by external terminals
When Pr. 59 is set to any of "1 to 3, 11 to 13" (remote setting function valid), the functions of the
RH, RM and RL signals are changed: RH ⇒ acceleration, RM ⇒ deceleration and RL ⇒ clear.

Remote setting function
External operation:
PU operation:
By setting Pr. 59 = "11 to 13", the speed can be decelerated to the frequency lower than the main
speed (set by the external operation frequency (except multi-speed setting) or PU operation
frequency).

* External operation frequency (other than multi-speed) or PU running frequency.
Example of the remote setting function (1)
Frequency set by RH/RM operation + external running frequen-
cy or PU running frequency (other than multi-speed).
(PU operation frequency when Pr. 79 = "3" (external, PU com-
bined)) and terminal 4 input
(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.)
