Rotary Switches for Configuration
On the back of the device, there are three rotary switches for configuring
■
Motor speed via S1
■
Start/stop ramp and direction of rotation via S2
■
Operating mode via S3
Figure 2.13
S1: Motor speed
S2: Start/stop ramp and direction of rotation
You can use rotary switch S2 to set the direction of rotation of the connected DC roller motors
(conveyor direction) and configure a start/stop ramp for the acceleration at the same time.
Five start/stop ramps can be configured for each direction of rotation. The slope of the
acceleration is constant and independent of the set maximum speed.
The ramp duration defines the time from stationary to maximum speed (U
S
= 10 V), or from
maximum speed to stationary. When the set motor speed is lower, the ramp duration is shorter
as well.
The following diagram shows the start behavior of the start/stop ramp using the example of the
setting "1000 ms."

Note!
Configuration Requires the Power Supply to Be Switched Off/On
The settings of the rotary switches are applied when the ZPA motor control module is switched
on. When a change is made to the configuration, you will need to shut down the power supply
to the ZPA motor control module and then switch it on again.
