Example
The encoder output signal will get routed to output 1 with a frequency divider of "4". The
output will get controlled by bit 5 of the object 60FE:01.
•
:08
h
= 1 (switch on routing)
•
:02
h
= 0405
h
(04XX
h
+ 0005
h
). The following apply:
•
04XX
h
: Encoder signal with frequency divider 4
•
0005
h
: Selection of bit 5 of the object 60FE
h
:01
Switching on the output is done with setting the object 60FE:01 to the value "20
h
".
Example
The brake pwm signal will get routed to output 2. The automated brake control is using the
bit 0 of 60FE:01, therefore this bit will be the control bit of the object 60FE:01
•
:08
h
= 1 (switch on routing)
•
:03
h
= 01080
h
(01XX
h
+ 0080
h
). The following apply:
•
01XX
h
: Brake pwm signal
•
0080
h
: Selection of the inverted bit 0 of the object 60FE:01
10.2 I
2
t motor overload protection
10.2.1 Description
!
WARNING
For stepper motors only the nominal current but no maximum current is specified. Therefore the
usage of I
2
t with stepper motors is used at the users own risk
I
2
t motor overload protection has the objective of preventing damage to the motor and simultaneously
operating it normally at its thermal limit.
