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
parameterize data bit DO2 accordingly.
For ITOH Denki, logical 0 corresponds to a direction of rotation to the left. The motor control
module switches the DIR control signal to high impedance.
For ITOH Denki, logical 1 corresponds to a direction of rotation to the right. The motor control
module switches the DIR control signal to AUX level.
Data Bit DO2
Switching the Motor Speed (DO3)
You can switch both motors to a slow speed via data bit DO3. The slow speed is determined
based on the set speed.
Data Bit DO3
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 parameterize 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.
