3.6 Parameter Setting of Servo Drivers
3.6.1 Parameter Setting of WISE Servo Driver
Monitor if the number of sent and received pulses
is correct by setting this parameter. In Weihong
control system, the correct quantity of pulses sent
by control card is detected by pulse inspection in
order to determine whether there is electrical
interference.
Command pulse No. per
motor circle
When it is set to “0”, parameters Pr009 and Pr010
are valid.

0.001 mm:
Pr009=10000
Pr010=pitch 5mm/ pulse equivalent 0.001mm=
5000
Pr009/Pr010=10000/5000=2/1

Unit: 0.1/s. Set it according to the actual situation.
Unit: 0.1Hz. Set it according to the actual

Unit: 0.1ms. Set it according to the actual
situation.
When the value of Pr008 is not “0”, it can be calculated in terms of the following formula:
Screw pitch 5mm
Command pulse No. per motor circle 5000
Pulse equivalent Mechanical deceleration ratio 0.001mm/ p
When screw pitch is 5mm and pulse equivalent 0.001, the value of Pr008 is “5000”.

Setting Value of Pr008
As shown above, the process is undergone in terms of the
setting value of Pr008, not affected by the settings of Pr009 and
Pr010.
