Technical Manual N5 (CANopen)
6 Operating modes
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.
6.2.2 Activation
To activate the mode, the value "2" must be set in object 6060
h
(Modes Of Operation) (see "CiA 402
6.2.3 Controlword
The following bits in object 6040
(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 acceleration ramp to the target speed. On a transition from "0" to "1", the motor
brakes according to the deceleration ramp and comes to a standstill.
6.2.4 Statusword
The following bits in object 6041
(statusword) have a special function:
•
Bit 11: Limit exceeded: The target speed is above or below the set limit values.
6.2.5 Object entries
The following objects are necessary for controlling this mode:
•
(Dimension Factor):
The unit for speed values is defined here for the following objects. If subindices 1 and 2 are set to
the value "1", the speed is specified in revolutions per minute.
Otherwise, subindex 1 contains the multiplier and subindex 2 the divisor of the fraction by which the
speed values are multiplied in revolutions per second to calculate the desired user unit, see User-
defined units. Object 2060
h
is used to select whether the revolutions are electrical (2060
h
= 0) or
mechanical (2060
h
= 1).
•
h
: Target Velocity.
The target speed is set here in user-defined units.
•
h
: Velocity Acceleration
This object defines the acceleration. Subindex 1 contains the change in speed, subindex 2 the
corresponding time in seconds. Both together are used to calculate the acceleration:
Delta time (6048
h
:2)
Delta speed (6048
h
:1)
VL velocity acceleration =
•
h
(Velocity Deceleration):
This object defines the deceleration (deceleration ramp). The subindices here are arranged as
described in object 6048
h
; the change in speed is to be specified with positive sign.
•
h
(Velocity Min Max Amount):
The limitations of the target speeds are specified in this object.
The minimum speed is set in 6046
h
:1
h
. If the target speed (6042
h
) falls below the minimum speed,
the value is limited to the minimum speed 6046
h
:1
h
.
The maximum speed is set in 6046
h
:2
h
. If the target speed (6042
h
) exceeds the maximum speed,
the value is limited to the maximum speed 6046
:2
h
.
•
(Velocity Quick Stop):
This object can be used to set the quick-stop ramp. Subindices 1 and 2 are identical to those
described for object 6048
h
.
The following objects can be used to check the function:
•
h
(Vl Velocity Demand)
•
h
(Vl Velocity Actual Value)
