Remote Setting Function (Pr. 59) - Mitsubishi Electric FR-A700 Instruction Manual

Parameter
6.10.4

Remote setting function (Pr. 59)

Even if the operation panel is located away from the enclosure, you can use contact signals to
perform continuous variable-speed operation, without using analog signals.

Remote function
59
selection
Pr. 59 can be used to select a digital motor potentiometer. Setting Pr. 59 to a value of "1" acti-
vates the frequency setting storage function, so that the stored value is also stored when the
power is switched off. The last frequency value is stored in the EEPROM. The delete instruction
only applies to the data stored in RAM.
Forward rotation
Acceleration
Deceleration
When Pr. 59 is set to any of "1 to 3" (remote setting function valid), the functions of the RH, RM
and RL signals are changed: RH ⇒ acceleration, RM ⇒ deceleration and RL ⇒ clear.
