6 Operating modes
The following applies here: cycle time = value of 60C2
:01
h
* 10
value of 60C2:02
seconds.
•
:02
h
(Interpolation Time Index): This object specifies the time basis of the cycles. Currently,
h
:02
h
=-3 is supported; this yields a time basis of 1 millisecond.
The following objects can be read in this mode:
•
h
(Position Actual Value)
•
(Velocity Actual Value)
•
(Following Error Actual Value)
6.8 Cyclic Synchronous Velocity
6.8.1 Overview
Description
In this mode, the controller passes a speed preset via the fieldbus at fixed time intervals (referred to in
the following as a cycle). The controller then no longer calculates any ramps, but rather only follows the
presets.
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.
Activation
To activate the mode, the value "9" must be set in object 6060

(Modes Of Operation) (see "CiA 402
Controlword
In this mode, the bits of controlword 6040
have no special function.
Statusword
The following bits in object 6041
(statusword) have a special function:
