Cause
Troubleshooting
Solution
1. The home switch is faulty.
● There is only high‑speed
searching but no low‑
speed searching during
homing.
● After high‑speed searching,
low‑speed searching in the
reverse direction applies.
If a hardware DI is used,
check whether the
corresponding DI function is
allocated to a certain DI in
group H03 and check the
wiring of this DI. Change the
DI logic manually and
observe the value of H0b.03
(monitored DI status) to
monitor whether the servo
drive receives corresponding
DI level changes. If the home
signal is Z signal but it
cannot be found, check the
condition of the Z signal.
2. The homing time limit is
too short.
Check whether the value of
H05.35h (time limit for
homing) is too small
Increase the value of H05.35.
3. The speed in high‑speed
searching for the home
switch signal is too low.
Check the distance between
the start position of homing
and the home switch. Then
check whether the setpoint
of 6099.01h is too low,
resulting in a long homing
process.
Increase the value of
6099.01h.
4. The setting of the home
switch is improper.
● Check whether the limit
signals at both sides are
activated.
● Check whether a limit
signal is activated
simultaneously with the
home signal.
Set the position of the
physical switch properly.
● E601.1: Homing switch error
Description:
The homing switch is set improperly.

Troubleshooting
Solution
The home switch is set
improperly.
Check whether the limit
signals at both sides are
activated.
Check whether the limit
signal and the deceleration
point signal/home signal are
both activated.
Check whether the positive
and negative position limits
are activated successively.
Set the position of the
physical switch properly.
