The polarity of the nominal voltage can be modified with this MP.
MP1040 is still active but for internal voltage between position and speed controller.
MP210 is only active for position encoders. The counting direction for the rotary encoder
is compensated with MP1950.

The ratio of grating periods of the linear encoder to the motor rotary encoder should be greater than
5 (see MP1970).
Example: 2000 lines per revolution for the rotary encoder
2 µm grating period with ROD
Grating period of rotary encoder:
Entry value for MP1955:
11-10 TNC 407/TNC 415/TNC 425
0 = positive
1 = negative
0 =linear encoder for position control
1 =motor rotary encoder for position control (for trimming
speed controller only)
