Description
Monitor if the number of sent and received pulse is
correct by setting this parameter. In Weihong control
system, the correct quantity of pulse sent by control
card is detected by pulse inspection in order to
determine whether there is electrical interference.

Typical values: pitch 5 mm, encoder resolution 10000,
deceleration ratio 1:1, pulse equivalent 0.001 mm:
Pr48=10000
Pr4B= pitch 5mm/ pulse equivalent 0.001mm=5000
So, Pr48/Pr4B=10000/5000=2/1
After the parameters are set, writing mode of EEPROM has to be selected. Please refer to the
following steps:
1) Press [MODE] button → Select [EEPROM]→ Enter mode [EE_SET];
2) Press SET button, showing [EEP ―];
3) Keep pressing UP direction key for approx. 3 seconds, then [EEP ――] will be displayed, and
then writing starts until [Start] is displayed.
If [Finish] is displayed after saving the parameters, it means successful modification. If [Reset] is
shown, alteration will be validated only after restarting the driver. If [Error] occurs, the write-in is a
failure, and another setting is needed.
