p9525 SI Motion redundant coarse position value relevant bits (CU)
Sets the number of relevant bits for the redundant coarse position value.
The encoder, which is used for safe motion monitoring on the Control Unit must
be parameterized in this parameter.
See also: p0414, r0472, p9325
The following applies to safety-related functions that have not been enabled (p9501
= 0):
When powering-up p9525 is automatically set the same as r0472
The following applies to safety-related functions that have been enabled (p9501 >
0):
p9525 is checked to ensure that it matches r0472.
Unit: Default value:
- 16
p9526 SI Motion encoder assignment second channel
Sets the number of the encoder that is used in the second channel (control, Motor
Module) for safe motion monitoring functions.
See also: p0187, p0188, p0189, p0430
For safety-related motion monitoring functions the redundant safety position actual
value sensing must be activated in the appropriate encoder data set (p0430.19 =
1).
For p9526 = 1, the encoder for the closed-loop speed control is used for the second
channel of the motion monitoring functions (1-encoder system). This setting is only
permissible when using a DQI encoder.
Unit: Default value:
- 2
p9529 SI Motion Gx_XIST1 coarse position safety most significant bit (Control Unit)
Sets the bit number for the safety most significant bit (MSB) of the Gx_XIST1
coarse position.
The encoder, which is used for safe motion monitoring on the Control Unit must
be parameterized in this parameter.
See also: p0415, r0475, p9329
The following applies to safety-related functions that have not been enabled (p9501
= 0):
When powering-up, p9529 is automatically set the same as r0475.
The following applies to safety-related functions that have been enabled (p9501 >
0):
p9529 is checked to ensure that it matches r0475.
Unit: Default value:
- 14
