Multifunction I/O Setup - JVL MIS17 Series User Manual

5.5
The MIS motor contain a dual RS485 port also called the Multifunction port, since it can
be setup for many purposes such as data I/O, pulses out from the internal encoder, and
pulses in from an external encoder. By RS485 means that its a bi-directional balanced in-
teface port which can also be configured as RS422 input or output used to for example
to transmit the internal encoder pulses to a connected PLC or similar.
The setup is not yet fully integrated in MacTalk but the following guide shows how to
setup the most common combinations.
!
Following setups are described in this chapter:
1 Internal encoder (H2 or H4 option only) is send out at multifunction channel A and B.
Link to description:
2 Quadrature signals from the internal pulse generator is sent to the multifunction chan-
nels. Link to description:
3 Same as #2 but in pulse/direction format instead of quadrature. Link to description:
Pulse/direction signals from the internal pulse
5.5.1 Configuration of the Multifunction port in general
The RS485 interface (dual) can be setup to output internal encoder signals, pulse/direc-
tion or quadrature signals from the internal pulse generator etc.
The registers mentioned below can be written by any supported protocol/interface, but
are not visible as fields in MacTalk. By using the RxP program, the 2 registers can be writ-
ten with 2 lines in the beginning of the program:
R223 XFIELD_DATA
R222 XFIELD_ADDR
Following text describe specifically which values that must be written into register 222
and 223 to obtain various outputs from the motor.

Multifunction I/O setup

Notice that the Multifunction port is 5V levels and it is destructive if operated
with voltages outside the voltage range 0 to 5V.
