Spindle

6.12.2 Speed Encoder of the Spindle
Digital speed control requires a shaft speed encoder:

Define the speed encoder input in MP113.x.
The TNC, with or without integral spindle DSP, monitors the reference mark
of the speed encoder. The monitor checks whether the line count for one
revolution from reference mark to reference mark is equal to the line-count
entry in the motor table. If differences occur, the DSP error message
C3A0 Incorrect reference position S
appears. If this happens, check the
speed encoder, encoder cable, and whether you have selected the correct
motor.
With a gear wheel encoder, even if it is properly installed, monitoring can
result in this error message due to its inherent inaccuracy:

In this case, switch the monitoring off with MP2221 bit 0 = 1.
The TNC, with or without integral spindle DSP, monitors the direction of
rotation. If the nominal value of current exceeds the limit value for a certain
time, the DSP error message
C380 Motor <spindle 1/2> not controllable
appears.
TNC with integral spindle DSP:
At lower speeds, high-frequency spindles only have a low amount of torque.
If such a spindle is having its speeds controlled, the tool changer may slightly
twist the spindle, causing the limit of current to be exceeded. This leads to the
above error message:

In this case, switch the monitoring off with MP2221 bit 1 = 1.
MP113
Speed encoder for the spindle
MP113.0
Speed encoder for the first spindle
Input:
0: No speed encoder input
15 to 20: Speed encoder inputs X15 to X20
60: Speed encoder input X60 (only on LE with integral spindle
DSP)
62 to 64: Speed encoder inputs X62 to X64
MP113.1
Speed encoder for the second spindle
Input:
0: No speed encoder input
15 to 20: Speed encoder inputs X15 to X20
62 to 64: Speed encoder inputs X62 to X64
MP2221
Current and speed controller monitoring functions
Input: %xx
Bit 0 – Monitoring the reference mark
0: Monitoring active
1: Monitoring inactive
Bit 1 – Monitoring the rotational direction (only with spindle
DSP)
0: Monitoring active
1: Monitoring inactive
