Data Description
8.2 Parameters for SINAMICS S120
p9522[0...7] SI Motion gearbox encoder (motor)/load numerator (Control Unit)
Sets the numerator for the gear between the encoder (or motor for encoderless
monitoring functions) and load. The active gearbox stage can be switched over
via PROFIsafe.
[0] = gear 1
[1] = gearbox 2
[2] = gearbox 3
[3] = gearbox 4
[4] = gearbox 5
[5] = gearbox 6
[6] = gearbox 7
[7] = gearbox 8
See also: p9521
The numerator of the gear ratio must be multiplied by the number of pole pairs
for the encoderless monitoring functions.
Example:
Gear ratio 1:4, number of pole pairs (r0313) = 2
- -- -> p9521 = 1, p9522 = 8 (4 x 2)
Unit: Default value:
- - 1
p9523 SI Motion redundant coarse position value valid bits (CU)
Sets number of valid bits of 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: r0470, p9323
- - after starting the copy function (p9700 = 57 hex), p9523 is set the same as
r0470.
Unit: Default value:
- - 9
p9524 SI Motion redundant coarse position value fine resolution bits (CU)
Sets the number of bits for the fine resolution of 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: r0471
- - after starting the copy function (p9700 = 57 hex), p9524 is set the same as
r0471.
Unit: Default value:
- - - -2
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 booting p9525 is automatically set the same as r0472
The following applies for enabled safety- -related functions (p9501 > 0):
- - p9525 is checked to ensure that it matches r0472.
Unit: Default value:
- - 16
