Using IndraDrive external encoder (EN2)

[tekin]

Hi,

I want to use the external encoder input of the drive(EN2) independently of the axis and as a counter. The servo motor will do its normal operation with its own encoder, while the external encoder input will measure the length of an ever-increasing rope. When the counter reaches a certain length, I should be able to reset the encoder value with the PLC program.

In summary, can I use the external encoder input for any other purpose, independent of the axis?

Thank you from now

My configuration is as follows:

PLC

IndraMotionMlc1 CML25 with sercos 3 

Inline modules

R_IB_IL_24_DI_16 (2 items)

R_IB_IL_24_DO_16 (2 items)

R_IB_IL_AI_8_SF (1 items)

R_IB_IL_AO_2_SF (2 items)

R_IB_IL_INC_IN (1 items)

Drive

HCS03.1E-W0100-A-05-LNBV
CSB01.1C-S3-ENS-EN2-NN-S-NN-FW
FWA MPB-08V08-D5-1-NNN-NN
MSK101D-0450-NN-M1-AP0-NNNN

Note:
We are currently using IB-IL-INC-IN-PAC encoder module for the rope counter, but the encoder module is sometimes affected by somethings and it counts by itself.

Since we cannot solve this problem excatly, we want to use the external encoder input of the drive.

Hi,

in a recent application we use the encoder 1 (motor encoder connect in X4) for to move the mechanic system, and an encoder 2 (external encoder connect in X8) for to check the movement of the material. The position of the encoder 2 was read from the parameter S-0-0053. The encoder was in module configuration and the reset was made automatically after the end of the module position.

Thank you for your reply.
I will try this. When auto reset with Modulo (there is only one Modulo setting under Scaling), will only Encoder-2 be reset or will both be reset?
Encoder-1 should not be affected.

best regard

Hi, 

the modulo has effect in both encoder. For to reset only the second encoder one possible way is to select the second encoder with S-0-520 and give a homing comand in the P-0-4077 control word. Look at the picture.

thank you again for reply, I will try
