2 Parameters
2.2 List of parameters
p0492 Maximum speed difference per sampling cycle / n_dif max/samp_cyc
Access level: 3
Can be changed: U, T
Unit group: -
Min
0.00 [rpm]
Description: Sets the maximum permissible speed difference within the current controller sampling time.
Dependency: Refer to: r1408
Refer to: F07902, F31118, A31418
Note: For a value of 0.0, the speed change monitoring is disabled.
If the speed difference exceeds the threshold value p0492, depending on p0491, either encoderless closed-loop
speed/torque control is selected or the drive is switched off with fault F3x118.
p0493[0...n] Zero mark selection input terminal / ZM_sel inp_term
Access level: 3
Can be changed: U, T
Unit group: -
Min
0
Description: Sets the input terminal for selecting the reference mark via BERO/switching signal when performing referencing with
several zero marks.
The encoder interface supplies the position of the reference mark, which was detected immediately after the positive
edge of the BERO signal.
Value: 0:
24:
25:
26:
27:
Dependency: Refer to: p0490
Note: Refer to the encoder interface for PROFIdrive.
The terminal must be set as input (p0728).
For p0493 = 0 (factory setting) the following applies:
- there is no logic operation between the reference mark search and an input signal.
For p0493 > 0, the following applies:
- the positive edge of the input signal is evaluated. If the negative edge is to be evaluated, signal inversion must be
parameterized via p0490.
- if a parameter change is rejected, a check should be performed as to whether the input terminal is already being
used in p0580, p0680, p2517, or p2518.
p0494[0...n] Equivalent zero mark input terminal / ZM_equiv inp_term
Access level: 3
Can be changed: U, T
Unit group: -
Min
0
Description: Selects the input terminal for connecting an equivalent zero mark (external encoder zero mark).
Value: 0:
24:
25:
26:
27:
Dependency: Refer to: p0490
Note: Refer to the encoder interface for PROFIdrive.
The terminal must be set as input.
