我在组态1500的工艺对象时，配置的是105报文，由于工艺需求，我想用外部编码器的值替换掉报文伺服上传过来的编码器器的值，并且在MC-PreServo内进行实现。发现组态里面有填写编码器反馈值的G1_XIST1的位，查资料发现这些位是用于细分，

由此发出了几个问题大家一起探讨：

1、编码器反馈值的G1_XIST1是反馈编码器一圈的脉冲数还是保存了编码器转过圈数的脉冲数，也就是说伺服传过来的G1_XIST1的数据格式；

2、G1_XIST1的值和细分的位数有什么联系；

3、伺服上的编码器是2500个脉冲每圈，细分位数和编码器每圈脉冲数有什么联系；

Hello,

would you please post in English here? Thank you.

When I configured the 1500 technology object, I configured the 105 message. Due to the process requirements, I want to replace the value of the encoder sent by the message servo with the value of the external encoder, and do it in the MC-PreServo. achieve. Found that there is a G1_XIST1 bit in the configuration that fills in the encoder feedback value. The data found that these bits are used for subdivision.

This raises several questions that everyone will discuss together:

1. G1_XIST1 of the feedback value of the encoder is the number of pulses of the feedback encoder or the number of pulses of the number of turns of the encoder, that is, the data format of the G1_XIST1 transmitted by the servo;

2. What is the relationship between the value of G1_XIST1 and the number of subdivided digits;

3. The encoder on the servo is 2500 pulses per revolution, and what is the connection between the number of subdivisions and the number of pulses per revolution of the Encoder;

Hello gaofei2013,

in international forum of Siemens it is common to post in English.
Please be so kind and write your next posts in English.
Thank you. 

Hi,

due to the fact that you say the encoder has 2500 pulses I assume you are maybe using V90 drive. So here in this FAQ it is described, which settings for the encoder have to be set at the TO:

Hello,

I do not understand that configuration because Cu250S-2 does not support Telegram 105 at all.
