3.3Connecting the AS-Interface and Auxiliary Power Flat Cable
The motor control module is connected to the AS-Interface network and the AUX auxiliary
power via the AS-Interface flat cable. The yellow flat cable is for communication and the black
flat cable is for the AUX auxiliary power. The permissible auxiliary power is 18 V ... 30 V.
Contact between the motor control module and flat cables is established v ia two metal
mandrels and using insulation piercing technology. The flat cables are routed through a hinged
cable guide. When closed, the cable guide is locked using a locking bracket and can be
opened again without the needs for tools.
The profiled flat cables have a narrow upper side (with a visibly offset profile edge) and a wide
under side (profile edge not visible). The cable guide allows the flat cables to be inserted on
both sides, for flexible connection of flat cables already laid in cable ducts. However, you must
make sure that the profile edge always points to the motor control module. Mechanical reverse
polarity protection prevents complete closure of the cable guide if the flat cable is inserted
incorrectly.
Caution!
If one is inserted incorrectly, the motor control module will not work.
If the flat cable is inserted in the cable guide in the wrong direction, the voltage is inverted. The
motor control module will not work. H owever, internal electrical reverse polarity protection
protects it against breakage.
Connecting Flat Cables on the Narrow Side
The profile edge is visible from above.
1. Open the cable guide. To do this, push the locking bracket (1) slightly to one side.
2. Insert the black AUX flat cable with the profile edge (4) to the motor control module into the
lower guide (see the module tag "Black AUX").
3. Insert the yellow AS-Interface flat cable with the profile edge (3) to the motor control module
into the upper guide (see the module tag "YELLOW").
4. Make sure that the profile edges of both flat cables are under the respective reverse polarity
protection (2, 5).
5. Close the cable guide. It must engage securely in the locking bracket (1).
The metal mandrels contact the strands in the flat cables.

Flat Cable Inserted Incorrectly
The figure below shows an incorrectly inserted flat cable. The profile edge (2) does not point to
the motor control module; the flat cable is therefore inserted with reverse polarity. The flat cable
is located on the reverse polarity protection (1) with a curvature, which means that the cable
guide cannot be closed completely (mechanical reverse polarity protection).

AS-Interface Communication Monitoring
The motor control module has a watchdog function. If there has been no communication with
the master for more than 40 ms, the motor control module sets the output data DO0...DO3 to
logical 0.
Starting/Stopping the Motors (DO0, DO1)
You can start or stop the motors separately via bits DO 0 and DO1. To start the motors, you
must set the corresponding data bit to logical 1. Via the shared SPEED control signal, the
motor control module uses an analog voltage value to actuate the respective motor that has
been switched on. The SPEED control signal is released for the relevant output only when data
bit DO0 or DO 1 is set. The analog voltage value corresponds to the set speed.

Switching the Motor Direction of Rotation (DO2)
You can switch the direction of rotation of the motors using the DIR control signal. The direction
of rotation signal applies to both motors. To control the direction of location, you must
param eterize data bit DO2 accordingly.
For ITOH Denki, logical 0 corresponds to a direction of rotation to the left. The motor control
module sw itches the DIR control signal to high impedance.
For ITOH Denki, logical 1 corresponds to a direction of rotation to the right. The m otor control
module sw itches the DIR control signal to AUX level.

Adjusting the Motor Speed (P0 ... P2)
You can adjust the speed via parameter bits P0...P2. This always applies to both motors
simultaneously. To do this, you must pa rameterize 1 of 8 predefined speed values. The speed
values correspond to analog voltage values.
If the master does not change the parameter bits when the AS-Interface network is switched
on, the 8th speed value (9.7 V) is set by default on the motor control module.
Geschwindigkeitswert (9,7 V) voreingestellt.
Using data bit DO3, you can switch the speed of both motors between fast and slow.
The motor control module issues the set control voltage to the motors via the SPEED control
signal as soon as the motors are switched on via data bits DO0 and DO1 (logical 1). The
control voltage is readjusted by the motor control module and is therefore independent of the
load within certain limits. If the control limits are exceeded due to an excessive load, the motor
control module issues a peripheral fault.

4.2Configuring the Start/Stop Ramps
Overview
To control the acceleration and to stop the motors, you can set 1 of 8 defined start/stop ramps
for the speed signal SPEED. These ramps always apply to both m otors simultaneously. The
ramp duration corresponds to the time from stopped to reaching the maximum speed or from
the maximum speed to stopped. The inclines of the ramps are constant for each of the 8 ramps
and independent of the set speed. The reference value for all ramps is the speed signal
SPEED = 9.7 V. For a lower parameterized speed, the ramp duration is proportionally shorter.

The ramp is not effective if the direction of rotation signal is switched when the motor is active.
In this case, the direction of rotation is reversed immediately.
Note!
Default Setting on Delivery
On outbound delivery, ramp no. 5 (500 ms) is the default.
Configuring Start/Stop Ramps
To adjust a start/stop ram p, you must change the motor control module to configuration mode.
The motor control module stores a new ramp configuration in the internal non-volatile memory.
This ramp is activated automatically after each switch-on. You can reconfigure a ram p as often
as required.
A prerequisite for configuration is that the flat cables for the AS-Interface and AUX are
connected. Communication must already be taking place between the master and motor
control module.
Note!
Configuration Mode Display via LEDs
If the motor control module is in configuration mode, the MOT1 and MOT2 LEDs flash
simultaneously at a frequency of approx. 2 Hz .
The configuration sequence consists of 9 steps. As part of this, defined data is transferred via
data bits DO0 ... DO3 and parameter bits P0... P3 between the m aster and the motor control
module. The master must keep the data and param eter bits constant for at least 10 ms for each
step. Longer intervals are possible as long as a period of 10 s is not exceeded for steps 1...6.
Configuring a new start/stop ramp involves the following phases:
■
In steps 1 ... 6, the master sends param eter values to the motor control module to activate
configuration mode (max. 10 s). For each step, DO0 ... DO3 must have the data value "4."
■
As soon as the motor control module is in configuration m ode, the 2 MOT1 and MOT2
LEDs start to flash.
18
■
In step 7, the master sends the selected ramp no. via DO0 ... DO3 to the motor control
module.
■
In step 8, the master sends the parameter value "4" via P0 ... P3 to the motor control
module. The motor control module stores the ram p number in the non-volatile memory.
■
In step 9, the master exits configuration mode. It sends the data value "4" via DO0 ... DO3
and the data value "7" via P0 ... P3. The motor control module switches to normal mode.
The MOT1 and MOT2 LEDs stop flashing.

Note!
Sequence for Com mand Transmission
For each step, you generally send the data value via DO0 ... D03 first, and then the parameter
value P0 ... P3. The following table depicts the contexts of the communication between the
master and the motor control module. The value "x" represents any of the values in the table.
Sequence for Configuring a Start/Stop Ramp
Send the following data values and parameter values to the motor control module:
1. For each of steps 1...6, send the data value "4" via DO0 ... DO3 as well as, via P0 ... P3, the
corresponding value from the parameter sequence 3,1,6,3,1,6.
2. If configuration mode is active, as step 7, send the required ramp no. via DO0 ... DO3 and
via P0 ... P3 the parameter value "6."
3. As step 8, send the ramp no. again via DO0 ... DO3 and via P0 ... P3 the parameter value
"4."
4. As step 9 send data value "0" via DO0 ... DO3 and via P0 ... P3 the parameter value "7."
The motor control module has stored the new start/stop ramp and switched back to
normal mode.
