Operation
4.2.2 Linear Servomotor Movement Direction
The linear servomotor movement direction can be reversed with parameter Pn000.0. This causes the travel
direction (+, -) of the shaft to reverse, but the encoder output pulse and analog monitor signal polarity do not
change. (Refer to 5.1.3 Monitoring Analog Signals.)
Before performing this operation. Motor Phase (Pn080.1) must be set correctly. For the setting method, refer
to Σ -V series User’s Manual, Setup, Linear Motor (SIEP S800000 44).
Note 1. The figures in the table above show the trace waveforms for the SigmaWin+.
2. Use the Feedback Pulse Counter (Un00D) to check the linear scale count.
