Objects for the Velocity Mode
The ramp generator follows the target speed while adhering to the set speed and acceleration limits. Bit
11 is set in object 6041
(internal limit active) when a limitation is active.

9.3 Profile Velocity
9.3.1 Special feature PD4C USB
Note
Because this motor controller is not fitted with a field bus, the following operating mode is only usable
with a NanoJ program.
Further information on programming and use of a NanoJ program can be found in the "Programming
with NanoJ" section.
9.3.2 Description
This mode operates the motor in Velocity Mode with expanded ramps. Unlike velocity mode (see
"Velocity"), the actual speed can be monitored via an external encoder in this mode.
Note
The limit switches - and therefore the tolerance bands - are active in this mode. See chapter
"Tolerance bands of the limit switches" for further information about the limit switches.
9.3.3 Activation
To activate the mode, the value "3" must be set in object 6060
