Motor control unit DCM31
8 / 35
- If the drive unit, despite the bar moving upwards in the 7 segment display, start up
in the “CLOSE” direction, the connection wires [Kl.7]+[Kl.8] must be switched over.
- The control unit learns the maximum motor current for each direction of travel.
- Motor adjustments are made in [M.A2]..[M.b0].
[Kl.9]+[Kl.10] output 12 V DC / stable
Terminal 9 = 12 V/DC stable, max. 40 mA
Terminal 10 = 0 V/earth
- e.g. for OSE connection
[Kl.10]+[Kl.11] output 24 V / DC unstable
Terminal 11 = 24 V/DC unstable, max. 200 mA
Terminal 10 = 0 V/earth
- e.g. for connecting the supply voltage for a photoelectric barrier
[Kl.12]+[Kl.13] relay output (floating)
- For connecting electric lock or other options, max. 24 Volt, 4 ampere.
- The function is set via [M.C4].
- The switched status is displayed via the yellow “OUT“ LED [X7].
[Kl.14]+[Kl.15] emergency stop
- Controls with floating contact can be connected to the emergency stop input.
- The behaviour of the control unit following an emergency stop is set via [M.b8].
- The contact must be closed in the idle condition (break contact).
- Several controls can be connected in series.
- An unused emergency stop input must be jumpered!
- The switched status of the emergency stop input is displayed by the red LED
behind the [Kl.14]+[Kl.15].
- The emergency stop input directly switches off the motor relay for safety reasons
and therefore is still active even if the electronics fail!
- In the event of an emergency stop command the motor stops immediately.
- If the emergency stop command while the motor is running, with the next pulse
command the gate travels in the “opposite direction” (away from the danger spot).
- If an emergency stop command is given while the gate is at a standstill, the gate
generally travels in the OPEN direction when the next pulse command is given.
[Kl.16]+[Kl.17]+[Kl.18] limit switch M1
Terminal 16 + 17 = limit switch M1 OPEN
Terminal 18 + 17 = limit switch M1 CLOSE
[Kl.19]+[Kl.20]+[Kl.21] limit switch M2
Terminal 19 + 20 = limit switch M2 OPEN
Terminal 21 + 20 = limit switch M2 CLOSE
- Controls with floating contact (break contact) can be connected at the limit switch
inputs.
- The contact must be closed in the idle condition (opened in the end position).
- The switched status is displayed via the LEDs behind the terminals. (LEDs lit in
end position, i.e. if limit switch pressed/opened)
- If [M.C6] = 00 or = 02, the limit switch inputs function and the LEDs are always off.
- Alternatively, drive units with integrated limit switches can be used [M.C6], which
interrupt the motor current in the relevant direction. The control unit then interprets
