Re bit 14, 15:
r0481.14 = 1 and r0481.15 = 0 can have one of the following causes:
- the encoder is parked.
- the encoder is de-activated.
- the encoder is being commissioned.
- no parameterized encoder available.
- encoder data set is being changed over.
r0481.14 = 1 and r0481.15 = 1 has the following significance:
An encoder error has occurred and the encoder position actual value (Gn_XIST1) is invalid.
Description: Display and connector output for the encoder actual position value Gn_XIST1 according to PROFIdrive.
Index: [0] = Encoder 1
[1] = Encoder 2
[2] = -
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
Description: Displays the encoder actual position value Gn_XIST2 according to PROFIdrive.
Recommendation: Possible causes:
Re Error code = 4097, 4098: Defective Control Unit hardware.
Re Error codes = 4099, 4100: Too many measuring pulses have occurred.
Index: [0] = Encoder 1
[1] = Encoder 2
[2] = -
Notice: The encoder position actual value must be requested using the encoder control word Gn_STW.13.
