Inovance SV670P Series Troubleshooting Guide

Description of Warning Codes
‑21‑
Cause
Confirming Method
Solution
The homing method value is
too large.
Check if the homing method
value exceeds the existent
homing mode (technology
segment homing, H22.70).
Change the value of H22.70.
● E730.0: Encoder battery voltage low
Cause:
The voltage of the absolute encoder battery is lower than 3.0 V.
Cause
Confirming Method Solution
The voltage of the absolute
encoder battery is lower
than 3.0 V.
Measure the battery voltage.
Use a new battery with the
matching voltage.
Note
E731.0 and E733.0 can trigger E730.0. See E731.0 and E733.0 for other solutions.
● E730.1: Inovance 2nd encoder battery voltage low
Cause:
Inovance 2nd encoder battery voltage is lower than 3.0 V.
Cause
Confirming Method
Solution
Inovance 2nd encoder
battery voltage is too low.
Measure the battery voltage.
Use a new battery with the
matching voltage.
● E831.0: AI2 zero offset too large
Cause
Confirming Method Solution
1. The wiring is incorrect or
interference exists.
Check the wiring according
to the correct wiring
diagram.
Use shielded twisted pairs
and shorten the circuit
length. Increase AI2 input
filter time.
2. The servo drive is faulty.
Disconnect AI1 and measure
whether the actual terminal
voltage exceeds 0.5 V.
If not, replace the servo
drive.
● E834.1: AI1 overvoltage
