6 Operating modes
6.3 Profile Velocity
6.3.1 Note regarding USB
Note
Because this controller is not equipped with a fieldbus, the following operating mode can only be used
with a NanoJ program.
You can find further information on the programming and use of a NanoJ program in chapter
Programming with NanoJ.
6.3.2 Description
This mode operates the motor in Velocity Mode with extended (jerk-limited) ramps.
Note
The limit switches and, thus, the tolerance bands are active in this mode. For further information on
the limit switches, see Limitation of the range of motion.
6.3.3 Activation
To activate the mode, the value "3" must be set in object 6060
(Modes Of Operation) (see "CiA 402 Power
6.3.4 Controlword
The following bits in object 6040
h
(controlword) have a special function:
●
Bit 8 (Halt): If this bit is set to "1", the motor stops. On a transition from "1" to "0", the motor accelerates
with the set start ramp to the target speed. On a transition from "0" to "1", the motor brakes and comes to
a standstill.
6.3.5 Statusword
The following bits in object 6041
h
(statusword) have a special function:
●
Bit 10 (target speed reached; Target Reached): In combination with bit 8 in the controlword, this bit
specifies whether the target speed is reached, if braking is taking place or if the motor is at a standstill
(see table).

6.3.6 Object entries
The following objects are necessary for controlling this mode:
●
h
(Velocity Demand Value):
This object contains the output of the ramp generator, which simultaneously serves as the preset value
for the speed controller.
