Initial value
Pr. 59 "remote setting function selection" 0
You can perform operation by changing the speed continuously with only the contact signals
without using the analog speed signal.

•
When "Yes" is selected for the remote setting function, the terminals assigned to the RH, RM and
RL signals in Pr. 180 to 187 "8.4 Selection of the Control Circuit Input Terminal Functions" provide
the acceleration, deceleration and clear functions.
•
While the RH signal is "ON", the speed increases according to the preset acceleration time. While
the RM signal is "ON", the speed decreases according to the preset deceleration time.
•
When "Yes" is selected for the speed setting storage function, the running speed at the time when
the start signal (STF or STR) is turned "OFF" is stored. If the start signal is not turned "OFF", the
running speed more than 1 minute after the RH or RM signal is turned "OFF" is stored.
•
When the running speed has been stored, merely switching power on again and inputting the start
signal starts operation at the stored running speed.
•
Turning "ON" the RL signal clears the stored speed and decelerates the motor to a stop.
•
Controlling the RH/RM signal with the start signal "OFF" varies the preset speed.
•
When the acceleration or deceleration signal turns ON, the preset speed varies according to the
slope set in Pr. 44 or 45 [Section 8.5.2]. The acceleration/deceleration times of the output speed
are as set in Pr. 7 and 8 [Section 8.5.2]. Therefore, the actual output speed varies at the longer
preset times.
•
The speed can be added to the preset speed other than the multi-speed.

MEMO
When the RH and RM signals are both "ON", the speed does not vary.
The RL signal is valid only when the RH or RM signal is "OFF".
After the clear signal (RL) has turned from ON to OFF, a restart should be made
(STF signal turned ON) often more than 1 min has elapsed. The output speed
provided when a restart made within 1 min is the output speed given after the clear
signal (RL) has turned OFF (multi-speed).
