Position Loop Gain 1 - Mitsubishi MELDAS MDS-C1 Instruction Manual

During SHG control even if the PGN1 setting value is the same, the actual position loop gain will be
higher, so the speed loop must have a sufficient response. If the speed loop response is low,
vibration or overshooting could occur during acceleration/deceleration in the same manner as
conventional control. If the speed loop gain has been lowered because machine resonance occurs,
lower the position loop gain and adjust.

Set 1900 as a standard for SHG control.
Set 100 as a standard for SHG control.
The SHG control is an optional function. If the option is not set in the CNC, the
alarm 37 (at power ON) or warning E4, Error Parameter No. 104 (2304 for
M60S/E60 Series CNC) will be output.
Always set with a combination of
26 33 38 47
these three parameters.
