Re Bit 04 and Bit 05:
The actual hardware only supports 1x or 4x signal evaluation.
Bit 5/4 = 0/0: Signal evaluation per period, 4x.
Bit 5/4 = 1/0: Illegal setting.
Bit 5/4 = 0/1: Signal evaluation per period, 1x.
Bit 5/4 = 1/1: Illegal setting.
Re bit 06:
If the function is active, when dn/dt monitoring responds, the speed actual value is internally frozen for a time equiv-
alent to two current controller clock cycles. The rotor position continues to be integrated. The actual value is then
re-enabled after this time has expired.
Re bit 11:
If the bit is set, the Sensor Module checks within a certain time grid whether the fault cause is still present. This
enables the Sensor Module to switch from the fault state to the operating state and provide valid actual values auto-
matically. The faults are displayed until the user acknowledges them.
Re bit 12:
Additional fault messages can be activated for extended fault diagnostics.
Re bit 13:
When the bit is set, for an incremental encoder with zero mark, the absolute value in Gn_XIST2 can be requested
via Gn_STW.13.
Re bit 26:
Track monitoring is de-activated for the square-wave encoders when the bit is set, even if the monitoring function is
selected in p0405.2.
p0438[0...n] Squarewave encoder filter time / Enc t_filt
Access level: 3
Can be changed: C(4)
Units group: -
Min
0.00 [µs]
Description: Sets the filter time for a squarewave encoder.
The hardware of the squarewave encoder only supports the following values:
0: No filtering
0.04 µs
0.64 µs
2.56 µs
10.24 µs
20.48 µs
Dependency: Refer to: r0452
Notice: If the filter time is too long, the track signals A/B/R may be suppressed and the appropriate messages output.
Note: The most suitable filter time depends on the number of pulses and maximum speed of the square-wave encoder.
The filter time is automatically corrected to the next value when entering a non-specified value. In this case, no
message is output.
The effective filter time is displayed in r0452.
p0439[0...n] Encoder ramp-up time / Enc ramp-up time
Access level: 3
Can be changed: C(4)
Units group: -
Min
0 [ms]
Description: Sets the ramp-up time for the encoder.
The encoder supplies stable track signals once this time has elapsed.
Notice: This parameter is automatically pre-set for encoders from the encoder list (p0400).
