■ E3.130: different DIs allocated with the same function
Cause:
The same function is allocated to different DIs
Probable Cause ConrmingMethod Corrective Action
1. The same function is
allocated to different
DIs.
View 2003-03h, 2003-05h, 2003-
07hto2003-31htocheckwhether
they are allocated with the same
non-zero DI function No.
Allocate parameters that have been allocated with
the same non-zero DI function No. with different DI
functions. Then turn on the control power again to
allowthemodicationstotakeeffect.Youcanalso
turn the S-ON signal OFF and give the reset signal to
makethemodicationtakeeffect.
■ E3.136: 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 parameters are
saved there or parameter values are inconsistent with the agreed value.
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theInovance
SV820 series, servo drive and 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the"1.6Cables"sectionon
page 21. The cable must be connected reliably
withoutscratching,breakingorpoorcontact.
MeasuresignalsPS+,PS-,+5V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theon-sitevibrationistoolarge,
resulting in encoder cable loosening and potential
damage to 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.
