ICA-8DIO4M1-G20-IO
Product Description
• Direction of rotation
• SpeedDifferent Functions Based on IODD9
• Start/stop ramps
Tip
If a motor output is not configured for a roller motor, pin 2 of the corresponding output can be
used as a digital power output, which is supplied from the auxiliary voltage PWR. A separate bit
for controlling the power output is available in the process data.
The output at pin 2 is resistant to overloading and short circuits. The roller motor supply is pro-
tected by a fuse.
The speed is expressed as a percentage. The output voltage for controlling the roller motor
speed is output between the configurable limits. The lower limit corresponds to 0 % of the max-
imum speed, the upper limit corresponds to 100 % of the maximum speed.
For details regarding connection, see chapter 3.5.
Braking Function
You can use the process data to activate a brake for each roller motor. An activated brake
causes the analog velocity output to be lowered to 0 V after reaching the lower limit. For some
roller motors, this is mandatory to activate the brake function. This setting has no effect on
Interroll EC310 roller motors, as these roller motors always brake.
Start/Stop Ramps
The configurable ramp duration defines the time from stationary (0 %) to maximum speed
(100 %), or from maximum speed to stationary. When the terminal velocity is lower, the ramp
duration is shorter.
General IO-Link Information
IO-Link is a standardized point-to-point IO technology (IEC 61131-9) between an IO-Link mas-
ter that controls communication and an IO-Link device that acquires or executes process val-
ues at the lowest sensor/actuator level. In addition to transmitting process data, IO-Link also
provides access to detailed identification, diagnostic and parameter data of the respective IO-
Link device.
IO-Link uses unshielded 3- or 5-wire cables with a maximum length of 20 meters between the
IO-Link master and IO-Link device, and enables transfer rates of 4.8 kbit/s (COM1), 38.4 kbit/s
(COM2), or 230.4 kbit/s (COM3). The IO-Link interface is backward compatible with the
24 V I/O signals specified in IEC 61131-2.
Different Functions Based on IODD
The module has two different process data structures - Standard (STD) and Extended (EXT).
Which structure is used depends on the IO-Link device ID that is set. While the standard pro-
cess data image assigns 8 bytes of input data and 6 bytes of output data, the extended process
data image uses 8 bytes of input data and 18 bytes of output data. In addition to the functions of
the standard process data image, the extended process data image enables control of the
start/stop ramps and continuous, real-time adjustment of the roller motor speed via the process
data.
