[Test mode]
Speed command auto-offset (speed mode)
● Function
In the speed mode, the motor will rotate slightly in spite of
a [0V] speed command voltage. This problem will happen
when the speed command voltage has an offset of a few
milli-volt. This function automatically removes the slight
rotation compensating the command voltage offset.
● Details of display
1st and 2nd digit: [So: speed command auto-offset]
3rd to 6th digit: Indicates current [Speed command offset]
Note: Though the minimum offset value is
possible to set [-9999], the indication for the
minimum is [-999] (lower three digits only). To
confirm the offset value, indicate the [tune
mode]→[9: speed command offset].
● Operations
(1) To function the [speed command auto-offset], press
the [ADJ] key at least 0.1 second.
⇒1st digit [S] flashes. It will now function.
(Pressing [ADJ] key at least 0.1 second again inhibits the operation.
(2) To function [speed command auto-offset], press the [SET] key.
