Objects for Velocity Mode
The ramp generator follows the target speed, remaining within the set speed and acceleration limits. As
long as a limit is active, bit 11 in object 6041
h
is set (internal limit active).

6.3 Profile Velocity
6.3.1 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.
6.3.2 Activation
To activate the mode, the value "3" must be set in object 6060
h
(Modes Of Operation) (see "CiA 402
Power State Machine").
6.3.3 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.
6.3.4 Statusword
The following bits in object 6041
h
(statusword) have a special function:
