Inputs

7.1.1

Synchronization

In case several sensors should measure the same target synchronously, you can synchronize the controllers with each
other. The sync output of the first controller IMC5x00-Master is connected to the sync inputs of further controllers, see
Chap. 5.4.9.
Master
Slave Sync/Trig
Slave TrigIn
If the controllers are operated using an EtherCAT interface, synchronization must be performed via EtherCAT.
7.1.2

Encoder

1
A maximum of two encoder values can be assigned to the measured data. They will then be issued and used as trigger
conditions. This exact assignment to the measured values is ensured by the fact that exactly the encoder values are
output that are exist in half of the exposure time of the measured value (the exposure time may vary due to the control).
Tracks A and B make it possible to detect directions. Each of the three encod-ers can be configured separately. The

Key Function

The Multifunction button of the controller has multiple functions. Detailed information is available in the Multifunction
section, see Chap. 6.4.
7.1.4

Input Level

For the TrigIn digital input, the logic level must be defined with which it is controlled.
Input level TTL / HTL
7.1.5

Termination

For the Sync/Trig digital input, the terminating resistor in the operating mode Synchronization > Slave in the last
controller of the series must be switched on.
Termination on / off
1) The reference tracks can be used as a third encoder, see
Grey shaded fields require a selection.
IMS5x00
First controller in the measuring chain; synchronizes all subse-
quent controllers.
Controller operates in dependence on the first controller. The
input expects TTL or HTL level.
The input expects TTL or HTL level and enables external synchro-
nization. The TrigIn input is controlled by an external synchroni-
zation source, e.g., a frequency generator. Min. 0.1 ... 6 kHz. It is
also possible to simultaneously synchronize multiple controllers
externally.
