A.6
Setting a non standard HTL encoder
Proceeding: manually configuring the encoder
1. Set p0010 = 4.
This allows the encoder parameters to be accessed.
2. Configure the encoder using the table below.
3. Set p0010 = 0.

p0408[0]
Rotary encoder pulse No.
(Factory setting: 2048)
Sets the number of encoder pulses.

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.

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.
Yes No

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.
