Setting value / Description / Note Device Supervisor Parameter set
P300
Servo Mode
(Servo Mode)
SK 520E or
higher
P
0 ... 1
{ 0 }
This parameter activates speed control with speed measurement via an incremental encoder.
This leads to a very stable speed behaviour up to motor standstill.
0 = Off
1 = On
NOTE: For correct function, an incremental encoder must be connected (see Section 2.2)
and the correct pulse number must be entered in parameter P301.
P301
Incremental encoder
(Incremental encoder resolution)
SK 520E or
higher
0 ... 17
{ 6 }
Input of the pulse-count per rotation of the connected encoder.
If the encoder rotation direction is not the same as the FI, (depending on installation and wiring),
this can be compensated for by selecting the corresponding negative pulse numbers 8...16.
0 = 500 pulses
1 = 512 pulses
2 = 1000 pulses
3 = 1024 pulses
4 = 2000 pulses
5 = 2048 pulses
6 = 4096 pulses
7 = 5000 pulses
8 = -500 pulses
9 = -512 pulses
10 = -1000 pulses
11 = -1024 pulses
12 = -2000 pulses
13 = -2048 pulses
14 = -4096 pulses
15 = -5000 pulses
16 = -8192 pulses
17 = + 8192 pulses
NOTE: P301 is also significant for position control via incremental encoders for SK 530E and
above. The pulse number is set here if an incremental encoder is used for
positioning (P604=1).
