B - 12 Errors Ver. 0002
LIST OF WARNINGS
A warning on the 7-segment display appears with an "A" instead of an "E" which is used to
display errors. Warnings indicate that the Drive is getting to an error limit.
1 Inside Overtemperature prior to error 107
2 Motor Overtemperature prior to error 108
3 Outside temperature at the heatsink prior to error 106
The warning temperature (KV1, KV5 or KV9, respectively) has been exceeded.
TROUBLESHOOTING
This section is intended to be an assistance to solve some of the typical problems that come
up when installing the Servo Drive system.
The synchronous motor runs away. The axis with encoder simulator runs away.
Wrong encoder absolute position offset, or Resolver installed wrong.
Change the counting direction of the encoder signals, modify EP3.
Motor with sinewave encoder whose parameters have been set for a squarewave encoder. Modify GP2.
The synchronous motor does not turn smoothly, it applies force but intermittently.
The power phases between the drive and the motor are not cabled correctly.
The signal phases between the drive and the rotor sensor are not cabled correctly.
The torque of the synchronous motor is low.
Check the system's current limit. CP20. Wrong encoder absolute position offset.
The encoder, or resolver, has moved from the correct position.
The synchronous motor is overheated
Wrong encoder absolute position offset. Motor calculated wrong. Vertical axis not compensated. Too
much friction.
After the setup and with the Drive active, the motor moves.
Resolver feedback has been selected while actually using an encoder, modify GP2.
The motor does not turn properly and makes a lot of noise.
The resolver cable shield is not connected to connector X4 of the drive module. Pin 26.
The motor moves with a lot of noise and when stopped, it seems to jerk.
The encoder cable shield is connected at the motor end.
The following error depends on motor speed.
It is due to the effect of the PI which varies depending on speed (SP1, 2, 4, 5, 6, 7). Try adjusting it so this
does not happen. Remember that the minimum following error is only required for machining not for
moving.
The motor makes noise and heats up.
The resolver or encoder is positioned wrong. The encoder or resolver cable shield is not connected.
