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.
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.
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 and the 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!
Default Setting on Delivery
On delivery, ramp no. 0 (no ramp) is the default setting.
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.
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.
