Pin Function Name Description
1 Digital Common 0V Reference potential for digital inputs/outputs
2
20 ...24V Input V
in
Voltage input when an external 24VDC
supply is used
V = 24VDC +20%/-15%
I
MAX
= 1A
3 Digital Common 0V Reference potential for digital inputs/outputs
4
24V-Output V
out
Approx. 24V output (max. 100 mA load)
V = 24VDC ± 25%
I
MAX
(Pin 4 +32) = 100 mA
5
Prog. Input LI11 I8 See Pins 8-12 Inputs according to:
IEC61131-2 Type 1
“0” = -3...5VDC
“1” = 15...30VDC
Scan time <= 1ms
LI02 digital lter reduces
false trigger due to relay
chatter, lter time 10-100msec
(adjustable)
6
Drive Enable I7 Enable/Disable; response time < 1ms;
Enable instantly turns off motor current
7
Prog. Input LI09 I6 When I1...16, I8 are assigned as speed
selection, I1>I2>...I8
When I1...I8 are assigned as direction
inputs, both cannot be signaled together
Inputs not used for speed selection can
be assigned special functions.
