Squarewave Encoder Filter Time / Enc T_Filt - Siemens SINAMICS DCM List Manual

2 Parameters
2.2 List of parameters
Note: A value of zero is displayed if an encoder is not present.
Re bit 00:
When the data logger (trace) is activated, in the case of a fault, data before and after the event are recorded (traced)
and saved in files on the non-volatile memory medium. Experts can then evaluate this data.
Re bit 01:
If bit = 0, the zero mark is evaluated by ANDing tracks A and B and the zero mark.
For bit = 1, the zero mark is evaluated depending on the direction of rotation detected. For a positive direction of
rotation, the positive edge of the zero mark is considered and for a negative direction of rotation, the negative edge of
the zero mark.
Re bit 02:
If the bit is set, in the event of a deviation less than the tolerance window for the zero mark (p4681, p4682), the
pulses per revolution are corrected. If the bit is not set, encoder fault F3x131 is triggered.
Re bits 05, 04:
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
equivalent 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 07:
If the bit is set, the encoder pulses which have not been corrected are added to p4688 at the zero mark.
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
automatically. 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.
Re bit 28:
Monitoring of the difference between incremental and absolute position in the case of linear encoders.
Re bit 29:
When the bit is set, the EnDat encoder is initialized under a certain speed and, therefore, with high accuracy. If
initialization at a higher speed is requested, fault F31151, F32151, or F33151 is output.
Re bit 31:
When monitoring is active, the levels of the individual track signals and the corresponding inverted track signals are
monitored separately.
