Motor control unit DCM31
23 / 35
- The settings for the length of the travel-out are entered via [M.A5]. The larger the
value the longer the smooth travel before the end position. During the teaching
rungs the starting point of smooth travel is determined separately for each direction
of travel and motor.
- Each time changes are made to [M.A1], [M.A2] and [M.A5], the force values and
travel paths are deleted and new teaching runs must be completed.
- The motor voltage affects the force values for forced stopping. After the motor
voltage has been changed the closing forces must be checked and if necessary
corrected via [M.A7]..[M.b0].
j) Motor voltage over travel path
- [M.A3] and [M.A4] can be used to separately set the voltage over the travel path for
motor 1 and motor 2. The smaller the value, the slower the gate moves (minimum
speed = 00, maximum speed = 20).
- The motor voltage influences the force values for forced stopping. If the motor
voltage is changed the closing forces must be checked and if necessary corrected
via [M.A7]..[M.b0].
- Each time a change is made to [M.A3] and [M.A4], the force values and travel
paths are automatically deleted and new teaching runs must be completed.
k) Smooth stop
- A stop command along the travel path causes slow coasting of the motor. It is not
stopped abruptly. (exception: forced stopping, SE, LS, emergency stop).
- There is no smooth stop in dead man's mode.
l) Light / warning light
- [M.b2] is used to set the function of the light/ warning light output.
- If a warning light is connected to the light output, the menu values 00 (for motor
running) and 04-07 (engine running+early warning) are provided. If 04 and 05 an
early warning of 4sec is given before engine running in OPEN and CLOSE-
direction and if 06 and 07 only before engine running in CLOSE direction.
- Menu values 04 and 06 are intended for a self-flashing warning light, in 05 and 07
the flashing is generated by the light relay.
- If [M.b2] = 08 or 09 the light relay switches if the gate is in OPEN or CLOSE end
position (M1+M2, in 1-leaf gate M1 only).
m) Emergency stop
- The emergency stop input directly switches off the motor relay for safety reasons
and is therefore is still active even if the electronics fail!
- If the emergency stop input is actuated the motor stops immediately.
- The switched status of the emergency stop input is displayed by the red LED
behind the terminals [Kl.14]+[Kl.15].
- If the emergency stop command is given while the motor is running, the next time
the pulse command is given, the gate travels in the “opposite direction” (away from
the danger spot).
- If an emergency stop command if given while the gate is at a standstill, in general
the gate opens the next time a pulse command is given.
- If [M.b8] = 00, after the emergency stop is actuated the automatic closing is
blocked until the next pulse/open/close/TÖ/radio command.
- If [M.b8] = 02 is set, the next gate travel after an emergency stop is with half speed
only.
