The Hilmot Motor Control Card is a field module with two sensor inputs and two electronic outputs for controlling DC roller motors.
The compact housing can be installed directly in support profiles or conduits. The connection to the AS-Interface network and power supply is made using the AS-Inter- face flat cable and insulation-piercing techno- logy. The pivoted flat cable guide is secured using a snap fit. No tools are required. The sensor inputs and motor outputs are connected via cable outputs with M8 round plug con- nectors (inputs 4-pole female cordset with knurled thumb screw, outputs 5-pole snap on female cordset). Power for the inputs and motors is provided by the external auxiliary voltage UAUX.
The current switching state of the sensor inputs is indicated by the IN LEDs. The FUSE LEDs show that the power supply is applied to both motors. The MOT LEDs indicate when the motors are in operation (stop/operation). The DIR LED indicates the status of the rotation signal. The activation of the fault signal by a motor is displayed with the ERR LEDs.
The motors can be switched on and off individually by means of AS-Interface databits D0 and D1. D2 controls the rotation signal. The AS-Interface parameters P0 ... P2 select the voltage for the speed signal. The rotation and speed apply to both motors.
A start/stop ramp can be set for the speed signal for the controlled acceleration and stopping of the motors. The ramp duration can be selected from eight default values and can be configured over a defined sequence of data and parameters. The ramp selected in this way is saved permanently and is activated automatically after each power-on. The number of the ramp is displayed by a short flash of the ERR2, IN1, and IN2 LEDS in binary code. If the ramp number is set as 0 (no ramp), the six LEDs MOT1 to IN2 flash to show this.
The ramp is not effective if the rotation signal is switched while the motor is running. In other words, the reversal of rotation direction occurs immediately.
Note: The communication monitor of the module deactivates the outputs if there is no communication between the AS-Interface and the module for more than 40 ms. The IN1 and IN2 inputs suppress impulses of less than than 2 ms. A signal indicating an overload of the input supply , an overload of the speed signal, or the absence of the external auxiliary voltage is also transmitted to the AS-Interface master via the "peripheral fault" function. Communication via the AS-Interface continues.
