Er.130: Different DIs allocated with the same function
Cause Confirming Methods Corrective Action
1. The same function
is allocated to different
DIs.
Check whether parameters in
groups H03 (H03-02 to H03-
20) and H17 (H17-00 to H17-
30) are set for the same non-
zero DI function.
Re-allocate the parameters that have been allocated
with the same non-zero DI function with different DI
functions. Then re-connect control power to make
modification take effect. Or set the S-ON signal to OFF
and give the reset signal to make modification take
effect.
2. The DI function No.
exceeds the number of
DI functions.
Check whether MCU program
is updated.
Restore default setting (H02-31 = 1), and power on the
servo drive again.
Er.131: Number of DO functions exceeding the limit
Cause Confirming Methods Corrective Action
1. The DO function No. exceeds the
number of DO functions.
Check whether MCU program
is updated.
Restore default setting (H02-31 = 1), and
power on the servo drive again.
Er.136: Data check error or no parameter stored in the motor ROM
Cause Confirming Methods Corrective Action
1. Servo drive model and
servo motor model do not
match.
View servo drive and servo motor nameplates
to check that the equipment you are using is
IS650P series servo drive and 20-bit servo
motor (-U2***) of Inovance.
Replace matched servo drive and
servo motor and power on the system
again. If you use IS650P series servo
drive and 20-bit servo motor (-U2***)
of Inovance, ensure that H00-00 =
14000.
2. A parameter check
error occurs or no
parameter is stored in
the serial encoder ROM
memory.
Check whether encoder cable you use is
standard configuration of Inovance. For cable
specification, refer to Chapter 3 in the IS650P
User Manual. The cable must not scratch,
break or be in poor contact. The cable must
be connected reliably.
Measure signals PS+, PS-, +5V and GND
at both ends of encoder cable and observe
whether signals at both ends are consistent.
For definition of signals, refer to Chapter 3 in
the IS650P User Manual.
Ensure that encoder cable you use is
configured by Inovance as standard.
Ensure that the cable is connected
to the motor securely and tighten the
screw on the drive side. If necessary,
use a new encoder cable.
Never bundle encoder cable and
power cables (RST, UVW) together.
3. Servo drive faulty.
The fault persists after servo drive is powered
on again.
Replace the servo drive.
Er.201: Overcurrent 2
Cause Confirming Methods Correctivee Action
1. References are
input simultaneously
at servo startup or
reference input is too
quick.
Check whether an reference is input
before the keypad displays "rdy".
The time sequence is: after the keypad
displays "rdy", set the S-ON signal (S-ON) to
ON and then input reference.
If allowed, add reference filter time constant
or increase acceleration/deceleration time.
