Setting a non standard HTL encoder

Proceeding: manually configuring the encoder
1. Set p0010 = 4.
2. Configure the encoder using the table below.
3. Set p0010 = 0.
Parameter Description
p0400[0] Encoder type selection (Factory setting: 0)
Selects the encoder from the list of encoder types supported by the firmware of the Control Unit.
0 No encoder
3001 1024 HTL A/B with zero mark
3003 2048 HTL A/B with zero mark
p0408[0] Rotary encoder pulse No. (Factory setting: 2048)
Sets the number of encoder pulses.
p0410[0] Encoder inversion actual value (Factory setting: 0000 bin)
Bit 00 1 signal: Invert speed actual value
Bit 01 Not relevant for the CU240D-2
p0425[0] Encoder, rotary zero mark distance (Factory setting: 2048)
Sets the distance in pulses between two zero marks. This information is used for zero mark monitoring.
p0430[0] Sensor Module configuration (Factory setting: 0000 0000 0000 0000 0000 0000 0000 0000 bin)
Bit Signal name
21 A one-off zero mark distance error is tolerated. In the event of a defect, the
fault F3x100/F3x101 does not appear, but alarm A3x400/A3x401 does.
25 Switch-off encoder voltage supply during parking
A bit-wise configuration is only possible if the corresponding property is also present in r0458.
p0437[0] Sensor Module configuration extended (Factory setting: 0000 0000 0000 0000 0000 1000 0000 0000 bin)
Bit Signal name
00 Data logger
01 Zero mark edge detection
04 Edge evaluation bit 0
05 Edge evaluation bit 1
06 Freeze the speed actual value for dn/dt errors
11 Fault handling after PROFIdrive
12 Activate additional messages
26 Deselect track monitoring
p0438[0] Squarewave encoder filter time (Factory setting: 0.64 [μs])
0 No filtering
p0439[0] Encoder ramp-up time (Factory setting: 0 [ms])
p0453[0] Pulse encoder evaluation zero speed measuring time (Factory setting: 1000 [ms])
If no pulses are detected from track A/B during this time, a speed actual value of zero is output.
This function is required for slow-running motors so that actual speeds close to zero can be output correctly.
For further information, please refer to the List Manual.
