Recommended actions:
Ensure that the position feedback device type selected in
P1 Device Type
(03.038) is correct for the position feedback device connected to the P1 interface
on the drive.
If wire break detection on the drive encoder input is not required, set bit 0 of
P1 Error Detection Level
(03.040) to 0 to disable the Encoder 2 trip.
If the trip is due to the digital incremental Z (marker signal) this is often not connected. Check that this trip is disabled by setting
P1 Termination Select
(03.039) to a value that disables the termination on this input, which will disable hardware wire break detection.
Check cable continuity.
Check wiring of feedback signals is correct.
Check encoder power supply is set correctly (
P1 Supply Voltage
(03.036)).
Replace the encoder.
Trip
Encoder 3
Value
191
Short description
The drive has detected an incorrect UVW phase angle while running (RFC-S mode only) or SINCOS phase error. The feedback device which has caused the trip
can be identified by the sub-trip number.
Sub-trip
Reason
1
Drive position feedback interface 1
2
Drive position feedback interface 2
Recommended actions:
Check encoder shield connections.
Ensure the encoder cable is one uninterrupted cable.
Check the encoder signal for noise with an oscilloscope.
Check the integrity of the encoder mechanical mounting.
For a UVW servo encoder, ensure that the phase rotation of the UVW commutation signals is the same asthe phase rotation of the motor.
For a SINCOS encoder, ensure that motor and incremental SINCOS connections are correct and that for forward rotation of the motor, the encoder rotates
clockwise (when looking at the shaft of the encoder).
Repeat the offset measurement test.
Trip
Encoder 4
Value
192
Short description
This trip indicates that the encoder communications has timed out or the communications position message transfer time is too long. This trip can also be caused
due to a wire break in the communication channel between the drive and the encoder. The feedback device which has caused the trip can be identified by the sub-
trip number.
Sub-trip
Reason
1
Drive position feedback interface 1
2
Drive position feedback interface 2
Recommended actions:
Ensure the encoder power supply setting (
P1 Supply Voltage
(03.036)) is correct.
Complete encoder auto-configuration (
P1 Auto-configuration Select
(03.041) = Enabled).
Check the encoder wiring.
Replace the feedback device.
Trip
Encoder 5
Value
193
Short description
This trip indicates that there is a checksum or CRC error, or the SSI encoder is not ready. The Encoder 5 trip can also indicate a wire break to a communications
based encoder.
Sub-trip
Reason
1
Drive position feedback interface 1
2
Drive position feedback interface 2
Recommended actions:
Check the encoder cable shield connections.
Ensure the cable is one uninterrupted cable - remove any connector blocks or if unavoidable minimise the length of any shield pigtails to the connector
block.
Check the encoder signal for noise with an oscilloscope.
Check
P1 Comms Bits
(03.035).
If using a Hiperface, EnDat or BiSS encoder, carry out an encoder auto-configuration (
P1 Auto-configuration Select
(03.041) = Enabled).
Replace the encoder.
Trip
Encoder 6
Value
194
Short description
This trip indicates that the encoder has indicated an error or that the power supply has failed to an SSI encoder. This trip can also indicate a wire break to an SSI
encoder.
