5.4.2 Wiring
The SINUMERIK 840D and the HLA module are supplied from the
SIMODRIVE line supply infeed or from the SIMODRIVE monitoring module via
the equipment bus. There must be at least one NE module in the equipment
group when an HLA module is used. No provision has been made for any other
type of voltage supply and failure to use the supply provided could damage the
unit.
Note
It is not permissible to operate an HLA module on its own with a SIMODRIVE
monitoring module!
Power is supplied to downstream electrical axes via the DC link busbars (40
mm
2
) of the carrier module.
One position encoder for each axis can be evaluated on the HLA module.
S X101: Axis 1
S X102: Axis 2
The measuring system must always be plugged into the connector of the asso-
ciated axis.

Function
1 PENC0 PENC2 Encoder power supply
2 M M Encoder power supply ground
3 AP0 AP2 Incremental signal for track A
4 AN0 AN2 Inverse incremental signal for track A
5 ENDATDAT0 ENDATDAT2 EnDat or SSI interface data signal
6 BP0 BP2 Incremental signal for track B
7 BN0 BN2 Inverse incremental signal for track B
8 XENDATDAT0 XENDATDAT2 Inverse EnDat or
SSI interface data signal
9 PSENSE0 PSENSE2 Remote sense encoder power supply (P)
10 RP0 RP2 Zero pulse/reference mark signal A
11 MSENSE0 MSENSE2 Remote sense encoder power supply (M)
12 RN0 RN2 Inverse zero pulse/reference mark signal A
13 M M Ground (for internal shields)
14 ENDATCLK0 ENDATCLK2 EnDat or SSI interface clock signal
15 XBMICLK0 XBMICLK2 Inverse EnDat interface clock signal
Note: The SSI encoder requires an external 24 V power supply
1) The permissible voltage range for the common mode component of the
individual encoder signals (AP. AN. BP, BP, RP, RP) is 1.5...3.5 V.
