77. Setting of spindle origin offset
Format  . default value: 
Set value of deviation of spindle origin
In case the position of machine origin when the spindle is assembled deviates from
the ideal position to the customer, this parameter may be used for adustment.
78. Setting of number of spindle feedback pulses
Format  default value: 46
Sets number of feedback pulses per revolution of spindle based on the number of
spindle encoding lines.
79. Setting of number of pulses in the spindle command
Format  default value: 46
Sets number of pulses to be generated by controller when spindle turns one
revolution.
1: For a servo spindle with a gear mechanism having a gear ratio of 3:4, i.e., spindle
rotates 4 turns when motor rotates 3 turns, the servo spindle rotates 1 turn when
receiving a pulse command of 1.
In the above eample, spindle rotates 1 turn when the spindle motor rotates .75
turns, meaning that the controller only needs to send out 75 pulses for the
spindle to rotate 1 turn. Therefore, the parameter shall be set to 75 instead of
1. Since the servo spindle encoder is installed at the electric machinery end,
therefore the number of pulses in the spindle feedback shall also be set to 75.
For the above conditions, suppose the encoder is installed at the spindle end
instead of the electric machine end, and the encoder is of 124 lines, then the
number of pulses in the spindle feedback shall be set to 46 4124.
80. Setting of number of tools
Format  default value: 
Used in combination with powered turret, maimum 1 tools.
81. Set up the Turret type by the actual condition of the machine
