MD30220 $MA_ENC_MODULE_NR[ n ]
Actual value assignment: Drive module number/measuring circuit number
System Value Meaning
840D sl x The number of the drive assigned using MD13050
$MN_DRIVE_LOGIC_ADDRESS[ x ] should be entered.
MD30220 $MA_ENC_MODULE_NR[ n ] = x, refers to:
MD13050 $MN_DRIVE_LOGIC_ADDRESS[ x ]
MD30230 $MA_ENC_INPUT_NR[ n ]
Actual value assignment: Input on drive module/measuring circuit module
System Value Meaning
840Dsl x Number of the encoder interface within the PROFIdrive telegram
Examples
PROFIdrive telegram 103
x = 1 → 1st encoder interface (G1_ZSW, G1_XIST1, G1_XIST2)
x = 2 → 2nd encoder interface (G2_ZSW, G2_XIST1, G2_XIST2)
PROFIdrive telegram 118
x = 1 → 1st encoder interface (G2_ZSW, G2_XIST1, G2_XIST2)
x = 2 → 2nd encoder interface (G3_ZSW, G3_XIST1, G3_XIST2)
Note
For SINAMICS S120:
- encoder 1 (G1_...): Motor encoder
- encoder 2 (G2_...): Direct measuring system
- encoder 3 (G3_...): Additional measuring system
MD30240 $MA_ENC_TYPE[ n ]
Encoder type of the actual value sensing (position actual value)
System Value Meaning
840D sl 0 Simulation (operation without encoder)
1 Incremental encoder
4 Absolute encoder
Note
Corresponds with PROFIdrive parameter p979
