Note: The hardware enable is powered up upon detection of state sense versus
transition sensitivity.
Step Action
6 Use the UniLink software to check/establish the following:
l Drive Parameters - Set/restore the drive parameters to the factory
default values.
l Supply voltage - Set the supply voltage to the actual mains supply
voltage.
l Servo Motor - Select the applicable BPH servo motor.
l Feedback - Ensure the feedback matches the feedback unit in the
servo motor.
7 Check safety devices such as hardware limit switches, emergency stop
circuitry and so forth.
WARNING!
MECHANICAL MOVEMENT HAZARD
Ensure personnel, tools and all other obstructions are clear of the
equipment.
Failure to observe this precaution can result in severe injury or
equipment damage.
8 Turn on the AC mains power supply.
9 Enable 24 Vdc on connector X3, terminal 15. Observe that 500 ms after
the power supply was switched on, the servo motor is motionless with a
standstill torque of M
0
.
10 Using the UniLink Oscilloscope Service Function, program a small 50-rpm
velocity command. If the servo motor oscillates, the Kp parameter in the
"speed controller" menu page must be adjusted.
Note: The Kp parameter may have to be adjusted after connecting the
load. Refer to UniLink on-line help for more tuning information.
