Description of Warning Codes
‑17‑
Cause
Troubleshooting
Solution
The MCU detects excessive
pulse increment fed back by
FPGA.
When H05.38 is set to 0
(encoder frequency‑division
output) or 2 (2nd encoder
frequency‑division output),
check whether the output
pulse frequency
corresponding to the motor
speed upon fault exceeds
the limit.
Output pulse frequency (Hz)
= Motor speed (rpm)/60 x
H05.17
Decrease the value of H05.17
(encoder frequency‑division
pulses) to allow the output
pulse frequency, within the
speed range required by the
machine, to drop below the
frequency upper limit
allowed by the hardware.
The input pulse frequency
exceeds 2 MHz or
interference exists in the
pulse input pins when
H05.38 is set to 1 (Reference
pulse synchronous output).
● High‑speed pulse input
pins:open‑collector input
terminals: PULLHI, PULSE+,
PULSE‑, SIGN+, SIGN‑;
single‑channel maximum
pulse frequency: 200 kpps.
● High‑speed pulse input
pins: differential input
terminals: HPULSE+,
HPULSE‑, HSIGN+, HSIGN‑;
single‑channel maximum
pulse frequency: 4 Mpps.
Decrease the input pulse
frequency to a value within
the frequency upper limit
allowed by hardware.
Note:
In this case, if you do not
modify the electronic gear
ratio, the motor speed will
decrease.
If the input pulse frequency
is high but is still within the
frequency upper limit
allowed by the hardware,
take anti‑interference
measures (use STP cable for
pulse input and set pin filter
parameter H0A.24 or
H0A.30). This is to prevent
false warnings caused by
interference pulses
superimposed to actual
pulse references.
● E550.2: External switchover wait warning
Description:
Incorrect task block switching.
Cause
Troubleshooting
Solution
If the external warning must
be kept to allow current
block to continue operating,
the keypad displays the
warning when current block
is done operating.
Check bit4–7 of the task
mode (H28.16–H28.31) of
current operation block.
The warning will be cleared
automatically when the next
block is triggered by the
external signal.
● E600.0: Inertia auto‑tuning failure
