Test operation
Connect the motor shaft to the machine shaft directly._
Run the machine and perform the following check:
(1) Does the true motor speed meet the given reference speed?
If no, make adjustment in accordance with the instruction
in 3.7.
Is motor rotation smooth?
Does any usual sound occur?
Does any foreign smell arise?
Is temperature of each bearing normal?
When it is verified that the motor and machine are in good
condition, operate the motor and machine under load condition
to check.
3.7 Adjustment of motor speed
All FR-SFJ controllers are adjusted, before shipment, in ac-
cordance with the order specifications.
When analog voltage
speed reference signal is used, however, voltage drop caused
by signal line may cause deviation, and requires fine adjust-
ment.
When uses option card SF-TLJ and is connected to M300
series CNC through bus line, or uses option card SF-DAJ for
digital speed reference signal, no deviation occurs and there-
fore readjustment is not required.
In this case, OD is to
be
set to 1000.
Adjustment procedure:
(1) Set speed reference signal to the forward run minimum
speed and record the motor speed displayed by the
ment LED readout of controller (record the speed as
When the desired motor speed is set
