2.2 List of parameters
Index: [0] = Checksum over SI parameters for motion monitoring
[1] = Checksum over SI parameters for actual values
[2] = Checksum over SI parameters for hardware
Dependency: Refer to: p9729
Refer to: F01680
p9729[0...2] SI Motion setpoint checksum SI parameters (processor 1) / SI Mtn setp CRC P1
CU240D-2_DP_F Access level: 3
CU240D-2_PN_F
Can be changed: C(95)
CU250D-2_PN_F

CU250D-2_DP_F
Min
0000 hex
Description: Sets the checksum using the checksum-tested Safety Integrated parameters for motion monitoring functions
(reference checksum).
Index: [0] = Checksum over SI parameters for motion monitoring
[1] = Checksum over SI parameters for actual values
[2] = Checksum over SI parameters for hardware
Dependency: Refer to: r9728
Refer to: F01680
r9732[0...1] SI Motion velocity resolution / SI Mtn v_res
CU240D-2_DP_F Access level: 3
CU240D-2_PN_F
Can be changed: -
CU250D-2_PN_F
Unit group: -
CU250D-2_DP_F
Min
- [rpm]
Description: Displays the velocity resolution for safety-relevant motion monitoring functions.
For index 0:
Displays the safe velocity resolution (load side). Setpoints for velocity limits or parameter changes for velocities
below this threshold have no effect.
For index 1:
Displays the safe velocity accuracy based on the safe encoder accuracy
Index: [0] = Actual velocity resolution
[1] = Minimum velocity resolution
Note: Index 0: This parameter does not provide any information about the actual accuracy of the velocity sensing. This
depends on the type of actual value sensing, the gear factors as well as the quality of the encoder being used.
Index 1: For a two-encoder system, with just non-safety capable encoders, this means the poorer value of the two
encoders. Index[1] takes into account the coarse resolution of the encoder only
r9733[0...2] CO: SI Motion setpoint speed limit effective / SI Mtn setp_lim
CU240D-2_DP_F Access level: 3
CU240D-2_PN_F
Can be changed: -
CU250D-2_PN_F
Unit group: 3_1
CU250D-2_DP_F
Min
- [rpm]
Description: Displays the necessary setpoint speed limit as a result of the selected motion monitoring functions.
Contrary to the parameterization of the SI limit values, this parameter specifies the motor-side limit value and not the
load-side limit value.
Recommendation: For the ramp-function generator, by appropriately interconnecting the speed limits p1051 and p1052 with r9733[0, 1],
a drive-based setpoint velocity limiting can be realized.
- CI: p1051 = r9733[0]
- CI: p1052 = r9733[1]
Additional limiting can also be activated using connector input p1085 and p1088.
