p0492 Square-wave encoder, maximum speed difference per sampling cycle /
n_dif max/samp_cyc
SERVO_S110-CAN, Can be changed: U, T
SERVO_S110-DP,
Data type: FloatingPoint32
SERVO_S110-PN
P-Group: Encoder
Not for motor type: -
Min
0.00 [rpm]
Description: Sets the maximum permissible speed difference within the current controller sampling time for squarewave encod-
ers.
When the value is exceeded, depending on p0491, either encoderless closed-loop speed/torque control is selected
or the drive is powered down.
Dependency: Refer to: F31118, A31418, F32118, A32418
Note: For a value of 0.0, the speed change monitoring is disabled.
if the set maximum speed difference is only exceeded for one sampling time of the current controller, then an
appropriate alarm is output. However, if the maximum speed difference is exceeded over several sampling times,
then a corresponding fault is output.

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 posi-
tive edge of the BERO signal.

Dependency: Refer to: p0490
Notice: For CU310, CX32, NX10 and NX15, only DI/DO 9, 10, 11 can be selected as fast inputs (refer to the Equipment
Manual).
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.
