6.8 Commissioning: Basic procedure
Pulse number
This field shows the number of pulses of the encoder used.
Fine resolution
This field shows the number of bits of the encoder control
word used.
Load revolutions / encoder revolutions
In this section you can parameterize a gear ratio for the en-
coders used. The gear ratio is the ratio of encoder revolu-
tions to revolutions of the drive shaft (load revolutions).
"Number of load revolutions" allows you to enter the
•
number of load revolutions.
"Number of encoder revolutions" allows you to enter the
•
number of encoder revolutions.
Gear ratio
Sets the denominator and numerator for the gearbox be-
tween the encoder (or motor for encoderless monitoring
functions) and load.
Here, you parameterize the number of encoder pulses for the
encoder that is used for safe motion monitoring on the Motor
Module.
Here, you parameterize the fine resolution for the encoder
that is used for safe motion monitoring on the Motor Module.
The mean value of the actual values of both channels is
calculated cyclically after actual value synchronization has
been activated, for example, for systems or machines with
slip. The maximum slip defined in p9549 is monitored once
per cross-check cycle (r9724).
If "Actual value synchronization" is not enabled, the value
parameterized in p9542 is used as tolerance value for the
cross-checking.
Actual value tolerance
Here, you set the tolerance for the crosswise comparison of
the actual position between the two monitoring channels
Velocity tolerance
Here, you set the maximum tolerance for the crosswise com-
parison of the actual velocity (only if actual value synchroni-
zation has been activated).
