5.3
Connecting 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 via 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 needsfor 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.
13
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. However, internal electrical reverse polarity protection
protects it against breakage.

AS-Interface Communication
Assigning the AS-Interface Data Bits
Four data bits are available for communication to take place between the motor control module
and the master. Three data bits are available for controlling the motors.
The following designations apply below:
■
DI0...DI3 for AS-Interface input data (motor control module to master)

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...DO2 to
logical 0.
Starting/Stopping Motors (D00, D01)
You can start or stop the motors separately via the DO0 and DO1 bits. To start motors, you must
set the corresponding data bit to logical 1. Via the joint SPEED control signal, the motor control
module actuates the respective motor switched on with an analog voltage value. The SPEED
control signal is released only when DO0 or DO1 data bit is set for the relevant output. 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 is valid for both motors together. For control purposes, you must parameterize
the DO2 data bit accordingly.
Logical 0, according to RDR BL3, corresponds to direction of rotation to the left. The motor
control module switches the DIR control signal to high impedance.

Adjusting the Motor Speed (P0...P2)
You can adjust the speed for both motors simultaneously only via the P0...P2 parameter bits. To
do this, you must parameterize one of eight predefined speed values. The speed values
correspond to analog voltagevalues.
If the master does not change the parameter bits when the AS-Interface network is switched
on, the eighth speed value (7.26 V) is set per default on the motor control module.
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 DO0 and DO1 data bits (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.

Reporting a Motor Fault (DI0, DI1)
The motor control module records a motor fault via the ERROR status signal. The motor control
module reports faults to the master using DI0 (motor 1) and DI1 (motor 2) data bits. In the event
of a motor fault, the motor control module sets the respective DI0 or DI1 data bit to logical "1."
This status is set if no motor is connected or the motor is not supplied with power if a fuse in the
motor control module is defective.

Configuration of the Start/Stop Ramps
Overview
To control the acceleration and to stop the motors, you can set one of eight defined start/stop
ramps for the speed signal SPEED. These ramps always apply to both motors simultaneously.
The ramp duration corresponds to the time from stopping to reaching the maximum speed or
from the maximum speed up to stopping. The inclines of the ramps are constant for each of the
eight ramps and independent of the set speed. The reference value for all ramps is the speed
signal SPEED = 10 V. For a lower parameterized speed, the ramp duration is proportionally
shorter.

Commissioning
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 delivery, ramp no. 0 (no ramp) is the default setting.
Configuring Start/Stop Ramps
To adjust a start/stop ramp, you must change the motor control module to configuration mode.
The motor control module stores a new ramp set in the internal nonvolatile memory. This ramp
is activated automatically every time the motor is switched on. You can reconfigure a ramp 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, MOT2, ERR1, ERR2, IN1, IN2
LEDs flash simultaneously with a frequency of approx. 2 Hz.
The configuration sequence consists of nine steps. Defined data and parameter values are
transmitted between the master and the motor control module via the DO0...DO2, DI0 ... DI3
data bits andthe P0 .. P2 parameter bits. The master must keep the data and parameter 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 one to six.
The configuration of a new start/stop ramp runs in the following phases:
■
In steps one to six, the master sends parameter values to the motor control module to
activate configuration mode (max. 10 s). DO0.. DO2 must have the value "4" in each step.
■
If the parameter sequence was correct, the motor control module responds to the master
via DI0.. DI2 on the last parameter value with "C
hex
." This response indicates that
configuration mode is activated. The six MOT1 ..IN1 LEDs flash.
■
In step seven, the master sends the selected ramp no. to the motor control module via
DO0 ..DO2.
■
In step eight, the master sends the parameter value "4" to the motor control module via
P0 .. P2. The motor control module stores the ramp number in the nonvolatile memory. It
responds to the master with "A
Hex
" via DI0 ..DI2.
■
In step nine, the master exits configuration mode. The master sends data value "4" via
DO0...DO2 and data value "7" via P0.. P2. The motor control module switches to normal
mode. The six MOT1 ..IN1 LEDs stop flashing.
Note!
Sequence for Command Transmission
For each step, you generally send the data value via DO0.. D02 first and then the parameter
value P0.. P2. The following table shows the contexts of communication between the master
and motor control module. The value "x" represents any of the values in the table.

Commissioning
Sequence for Configuring a Start/Stop Ramp
Send the following data values and parameter values to the motor control module:
1.
In accordance with steps one to six, for each step send the data value "4" via DO0...DO2 and
then via P0...P2, a value of the parameter string 3,1,6,3,1,6 one after the other.
2.
If configuration mode is active, send the required ramp number via DO0...DO2 and the
parameter value "6" via P0...P2 as step seven.
3.
As step eight, send the ramp number again via DO0...DO2 and parameter value "4" via
P0...P2.
4.
As step nine, send data value "0" via DO0...DO2 and parameter value "7" via P0...P2.
The motor control module has stored the new start/stop ramp and switched back to
normal mode.

Troubleshooting during Configuration
The following table describes the behavior of the motor control module if a fault occurs during
the nine-step configuration process.
Fault Scenarios
Step
Possible fault
Motor control module reaction
1 to 6
■
Incorrect data or parameter values or
■
steps 1 to 6 take longer than 10 s
Motor control module remains in normal mode
7 or 8
Incorrect data or parameter values
■
Motor control module responds with "E
hex
"
via DI0 ... DI3 and remains in configuration
mode.
■
The motor control module switches to
normal mode only when the master sends
"0" via DO0 ... DO2 and "7" via P0 ... P2.
■
If "0" or "7" has already been set by the
master in one of these steps, the motor
control module switches to normal mode
immediately without sending a response.
The stored ramp is not changed.
