- 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
Description: Displays the encoder actual position value Gn_XIST2 according to PROFIdrive.
Index: [0] = Encoder 1
[1] = Encoder 2
[2] = Encoder 3
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.
4: Cancellation, reference block search (e.g. reference mark not available or input terminal for external zero mark
not set).
5: Cancellation, fetch reference value (e.g. illegal change from reference mark search to flying measurement).
6: Cancellation, flying measurement (e.g. input terminal for probe not set).
7: Cancellation, fetch measured value (e.g. illegal change from flying measurement to reference mark search).
8: Abort, absolute value transfer.
3841: Function not supported.
4097: Abort, reference mark search due to an initialization error.
4098: Abort, flying measurement due to an initialization error.
4099: Abort, reference mark search due to a measuring error.
4100: Abort, flying measurement due to a measuring error.
Description: Displays the encoder control word Gn_STW according to PROFIdrive for diagnostics.
Index: [0] = Encoder 1
[1] = Encoder 2
[2] = Encoder 3
