E1.136: Data check error or no parameter stored in the motor ROM
Cause:
When reading parameters from the encoder ROM memory, the servo drive detects that no
parameter is saved there or parameter values are inconsistent with the agreed values.
Probable Cause Conrming Method Corrective Action
1. The servo
drive model and
the motor model
do not match.
View the servo drive and servo motor
nameplates to check that the equipment
used is an Inovance IS810 series servo
drive and a matching servo motor.
Replace the matching servo
drive and servo motor.
2. A parameter
check error
occurs or no
parameter is
stored in the
serial increment
encoder ROM
memory.
Check whether the encoder cable is used
according to the standard conguration.
For cable specication, refer to 2.4
Matching Cables. The cable must be
connected reliably and must not be
damaged, broken, or under poor contact.
Measure signals PS+, PS-, +5 V and GND
at both ends of the encoder cable and
observe whether signals at both ends are
consistent. For the denition of signals,
refer to Hardware wiring.
Use the recommended encoder
cable. Ensure that the cable
is connected to the motor
securely and tighten the screws
on the drive side. If necessary,
use a new encoder cable.
Never bundle encoder cable
and power cables (RST, UVW)
together.
3. The encoder
wiring is incorrect
or disconnected.
Check the encoder wiring.
Check whether on-site vibration is
excessively intense, which loosens the
encoder cable or even damages the
encoder.
Connect the encoder cable
correctly.
Re-connect the encoder cable
securely.
4. The servo
drive is faulty.
The fault persists after the servo drive is
powered on again.
Replace the servo drive.
E1.150: STO input protection
Cause:
STO input protection
E1.201: Overcurrent
Cause:
Hardware overcurrent is detected.
Probable Cause Conrming Method Corrective Action
1. References
are input
simultaneously
at the servo drive
startup or the
reference input
is too early.
Check whether a reference is input before
the keypad displays "ry".
The time sequence is: After
the keypad displays "ry", turn
on the S-ON signal and then
input a reference.
If allowed, add reference
lter time constant or
increase acceleration/
deceleration time.
3. The motor
cables are in
poor contact.
Check whether the servo drive power cables
and motor UVW cables are loose.
Tighten the cables that are
loose or are disconnected.
