1)First, it is important that the motors 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 doesnt come on
,please check the proper value of the power supply with
a multimeter).
WARNING: 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 motors 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).
