9.2 Parameters for SINAMICS S120
p9522[0...7] SI Motion gearbox encoder (motor) / load denominator (Control Unit)
Sets the numerator for the gear between the encoder (or motor for encoderless
monitoring functions) and load. The actual 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
For the encoderless monitoring function, the numerator of the gear ratio must be
multiplied by the number of pole pairs.
Example:
Gear ratio 1:4, number of pole pairs (r0313=2
→ p9521 =1, p9522 = 8 (4x2)
Unit: Default value:
- 1
p9523 SI Motion redundant coarse position value valid bits (CU)
Sets the 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 - p9523
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
