Description of Warning Codes
‑16‑
● E110.0: Frequency‑division pulse output setting error
Description:
The frequency‑division output setpoint (H05.17) exceeds the encoder resolution.
Cause
Troubleshooting
Solution
The number of frequency
divisions (quadrupled)
exceeds the motor
revolutions
Check the value of H05.17
Adjust the value of H05.17
on the basis of the motor
revolutions
● E121.0: Duplicate S‑ON command
Description:
A redundant S‑ON signal is sent when some auxiliary functions are used.
Cause
Troubleshooting
Solution
The external S‑ON signal is
active when servo drive is
enabled internally.
Check whether the following
auxiliary functions are used:
Check whether DI functions
(H0d.02, H0d.03, and
H0d.12) are used and
whether FunIN.1 (S‑ON
signal) is active.
Deactivate the DI assigned
with FunIN.1 (both hardware
DI and virtual DI).
● E122.0: Multi‑turn absolute encoder setting error
Description:
The motor does not match the absolute position mode or the motor code is set
improperly.
Cause
Troubleshooting
Solution
The motor does not match
the absolute position mode
or the motor code is set
incorrectly.
1. Check the motor
nameplate to see whether
the motor is configured
with a multi‑turn absolute
encoder.
2. Check whether H00.00
(motor code) is set
properly.
Reset H00.00 (motor code)
according to the motor
nameplate or use a suitable
motor.
● E510.0: Frequency division output overspeed
Description:
The single‑channel output pulse frequency exceeds the frequency upper limit
allowed by the hardware (4 MHz) when pulse output is used (H05.38 = 0/1/2).
