7.25.10 Idle Clock Pre-Scaler (Object 0x40F3)
Object 0x40F3 transmits the pre-scaling factor for the speed measurement.
Design of the data bytes:
The IdleReference prescaler is used to determine the time base for measur-
ing the time between two edges on the counter inputs. The following
applies:
f
CLK
: 32000000 Hz
Clock [Hz] is an internal module time base.
