Note
The encoder signal is only output if using an encoder, not with Hall sensors.
On any change of the "encoder signal" (6063
h
) or the current position (6064
h
in user-defined units)
by an increment, a pulse is output at the digital input (for frequency divider 1). Take this into account
when selecting the frequency divider, especially when using sensors with low resolution (such as Hall
sensors).
Example
The encoder signal (6063
h
) is to be applied to output 1 with a frequency divider 4. The output
is to be controlled with bit 5 of object 60FE:01.

7.2 I
2
t Motor overload protection
7.2.1 Description
Note
For stepper motors, only the rated current is specified, not a maximum current. No liability is therefore
assumed when using I
2
t with stepper motors.
The goal of I
2
t motor overload protection is to protect the motor from damage and, at the same time, operate
it normally up to its thermal limit.
