Basic function principles
KL2532/KS2532, KL2552/KS2552 16 Version: 3.2.0
3 Basic function principles
3.1 Basic principles
The KL2532/KS2532 DC motor terminal integrates two compact DC motor output stages up to 24 W in a
very compact design.
The KL2552/KS2552 DC motor terminal integrates two compact DC motor output stages up to 250 W in a
very compact design.
General functions
Enable/Readiness for operation
For activating the output stage enable bit CB1.5 [ } 47] has to be set. If the terminal is in an error-free state
at the time, it sets ready bit SB1.4 [
}
48] as acknowledgement. If the terminal is ready to operate, it indicates
this by setting "Ready to Enable" ( R0.2 [
}
53] ). Directions of rotation are indicated by bit R0.4 [
}
53]
(Moving Positive) and R0.5 [
}
53] (Moving Negative).
Set / delete position
The user can set or delete the current position value. Register R5 [
}
54] is used as reference. A rising edge
at bit CB1.1 [
}
47] sets the current position, and the acknowledgement is provided through status bit SB1.1
[
}
48] .
Latch functions (only KL2552/KS2552)
The internal encoder offers the option of registering a latch event. A latch event can be generated via the
digital input signals.
The terminal response to the latch events is activated as follows:
• Setting the control bit CB1.2 [
}
47] activates the rising edge at the digital input (highest priority)
• Setting the control bit CB1.3 [
}
47] activates the falling edge at the digital input (second-highest
priority)
Once the user has enabled the function, during the next latch event, the terminal saves the current position
value and indicates this by setting status bit
SB1.2 [ } 48] . Reading of latch values must be initiated by
setting CB1.4 [ } 47] , which causes the latch value to be mapped in the DataIN process data (the terminal
indicates this via status bit SB1.3 [ } 48] ).
Reading the latch value
The enable that was set previously must be retained while reading out the latch value. The latch
value is lost if enable is cancelled!
Manual and automatic torque reduction
A torque reduction can be achieved in two ways:
• R32.10 [
}
56] = 0: The torque is reduced (to the value in R41 [
}
58] or R49 [
}
59] ), if CB1.0 [
}
47] =
1. The terminal acknowledges this by setting SB1.1 [
}
48] .
• R32.10 [ } 56] = 1: The torque is automatically reduced, if the process input data exceed the values
configured in R45 or R48.The torque is reduced automatically if the process input data exceed the
settings configured in
R45 [
}
59] or R48 [
}
59] . The reduction is deactivated, if the process input data
fall below a value of R45 or R48 - 2%.
R41 (reduced torque) and R45 (torque threshold) are used for the positive direction of rotation.
