5. The position reference
increment is too large.
Position control mode:
● In CSP mode, check the
gear ratio 6091.01h/
6091.02h to determine the
position reference
increment for an individual
synchronization period and
convert it to the speed
information.
● In PP mode, check the gear
ratio 6091.01h/6091.02h
and determine the 6081h
(Profile velocity).
● In HM mode, check the
gear ratio 6091.01h/
6091.02h, and determine
6099.01h and 6099.02h.
● CSP: Decrease the position
reference increment per
synchronization period.
The host controller should
cover the position ramp
when generating
references.
● PP: Decrease the value
6081h or increase the
acceleration/deceleration
ramp (6083h, 6084h).
● HM: Decrease 6099.01h and
6099.02h or increase the
acceleration/deceleration
ramp (609Ah).
Decrease the gear ratio
according to actual
conditions.
6. The servo drive/motor is
faulty.
Monitor the operation
waveform through the
oscilloscope function in the
software tool: position
references, position
feedback, speed references,
and torque references.
If the position reference is
not 0 but the position
feedback is always 0, replace
the servo drive or motor.
● EB01.0: Position reference increment too large
Description:
The pulse reference increment exceeds the excessive reference threshold three
times consecutively.
Cause
Troubleshooting
Solution
The pulse reference
increment exceeds the
excessive reference
threshold three times
consecutively.
Check whether the baud
rate of pulse reference input
exceeds H0A.09.
1. Increase the value of
H0A.09.
2. Reduce the baud rate of
pulse input.
● EB01.1: Individual position reference increment too large
Description:
The target position increment is too large.
