Co: Encoder Actual Position Value Gn_Xist2 / Enc Gn_Xist2 - Siemens SINAMICS G150 Manual

- The update time in isochronous operation and with position control (EPOS) corresponds to the position controller
clock cycle p0115[4].
- The update time in non-isochronous operation or without position control (EPOS) comprises the following:
Update time = 4 * least common multiple (LCM) of all current controller clock cycles (p0115[0]) in the drive group
(infeed + drives). The minimum update time is 1 ms.
Example 1: infeed, servo
Update time = 4 * LCM(250 µs, 125 µs) = 4 * 250 µs = 1 ms
Example 2: infeed, servo, vector
Update time = 4 * LCM(250 µs, 125 µs, 500 µs) = 4 * 500 µs = 2 ms
r0482[0...2] CO: Encoder actual position value Gn_XIST1 / Enc Gn_XIST1
VECTOR_G Can be changed: -
Data type: Unsigned32
P-Group: Encoder
Not for motor type: -
Min
-
Description: Display and connector output for the encoder actual position value Gn_XIST1 according to PROFIdrive.
Index: [0] = Encoder 1
[1] = Encoder 2
[2] = Encoder 3
Note: - this value is reset if necessary when the "parking encoder" (r0481.14) function is de-selected.
- in this value, the measuring gear (p0432, p0433) is only taken into account when the position tracking is activated
(p0411.0 = 1).
- The update time for the position control (EPOS) corresponds to the position controller clock cycle p0115[4].
- The update time in isochronous operation corresponds to the bus cycle time r2064[1].
- The update time in isochronous operation and with position control (EPOS) corresponds to the position controller
clock cycle p0115[4].
- The update time in non-isochronous operation or without position control (EPOS) comprises the following:
Update time = 4 * least common multiple (LCM) of all current controller clock cycles (p0115[0]) in the drive group
(infeed + drives). The minimum update time is 1 ms.
Example 1: infeed, servo
Update time = 4 * LCM(250 µs, 125 µs) = 4 * 250 µs = 1 ms
Example 2: infeed, servo, vector
Update time = 4 * LCM(250 µs, 125 µs, 500 µs) = 4 * 500 µs = 2 ms

CO: Encoder actual position value Gn_XIST2 / Enc Gn_XIST2

ENC Can be changed: -
Data type: Unsigned32
P-Group: Encoder
Not for motor type: -
Min
-
Description: Displays the encoder actual position value Gn_XIST2 according to PROFIdrive.
Recommend.: Possible causes:
Re Error code = 4097, 4098: Defective Control Unit hardware.
Re Error codes = 4099, 4100: Too many measuring pulses have occurred.
Notice: The encoder position actual value must be requested using the encoder control word Gn_STW.13.
Note: - in this value, the measuring gear (p0432, p0433) is only taken into account when the position tracking is activated
(p0411.0 = 1).
- if GxZSW.15 = 1 (r0481), then an error code with the following significance is located in Gx_XIST2 (r0483):
1: Encoder fault.
2: Possible position shift in Gx_XIST1.
3: Encoder parking not possible.
