Configuration
2.1.2.10.2.2
Acceleration Factor
The value for the acceleration factor (Acc_Multiplier) is determined by the
bits Acc_Range_Sel in control byte 2 (C2.2 and C2.3). If both of these bits are
zero (0), the value for the parameter Acc_Fact in the configuration table is
used.
Acc_Range_Sel
Acc_Multiplier
(acceleration factor)
Acceleration period T to f
at max. acceleration 32767
Note
If Acc_Range_Sel = 0 and configuration parameter Acc_Fact = 0, the variable
Acc_Multiplier is set to 8.
Acceleration is determined by the output data Acceleration (D2 and D3) and
the prescaler Freq_Prescaler and by the acceleration factor Acc_Multiplier.
a = Acceleration * Acc_Multiplier / Freq_Prescaler [Hz/s]
The permissible acceleration range is 1 ... 32767.
Acceleration is set in [Hz/s] when the acceleration factor Acc_Multiplier is
selected equal to the prescaler Freq_Prescaler.
Note
The bits Acc_Range_Sel may only be modified when the control system is
deactivated! These bits are therefore only accepted when Enable is not set.
