Force control

Qcommand	Direction	pdiff. command	Direction	Track traveling	Force control
+5,0 V		+3,5 V		with 50 % vmax.	after track traveling to 35 % of pdiff. max.
+7,5 V		-2,0 V		with 75 % vmax.	not possible
-3,3 V		-4,8 V		with 33 % vmax.	after track traveling to 48 % of pdiff. max.
-10,0 V		+8,0 V		with vmax.	not possible
A command value of at least ±0.3 V must be specified!
The numerical values listed in the table are examples, the signs of the values are decisive.
