1)First, it is important that the motors shaft is free from
the load and be ready to stop the main power supply
quickly, if necessary.
It is also important that the motor is fixed to a proper
stand.
Please ensure that the ref signal is zero (0).
2)Apply power to the drive.
In normal situations,after a delay of about 1 second,the
green
OK
LED will come on.
The motor must be still. (If the LED doesnt come on
,please check the proper value of the power supply with
a multimeter).
W A R N I N G :
If the motor is driven by
C.N.C.
, use the
ref in manual mode with the servo error disabled.
(Space loop disabled).
3)Enable the drive; PWM ON active.
A good rule is to provide the enable after the power
supply .
Check that the motor is stationary or turns slowly due to a
signal offset,this means that the tacho polarity is correct.
If the motor rotates in an opposite direction to the expected
one,switch off and reverse the motor and tachogenerator
connections .
WARNING:
After switching off,wait about 15 seconds
before re-applying power to the drive in order to avoid
problems.
4)Increase the speed reference up to one(1) volt and
check the sense of the motors rotation. (If the motor
rotates in the opposite direction of the expected
one,reverse the motor and tachogenerator connections
or reverse the speed reference connections).
