Description: Displays the checksum over the checked Safety Integrated parameters of the motion monitoring functions (actual
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: p9729
Refer to: F01680
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
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
