5.2 Expansion Module MAC00-B1/B2/B4
• Multifunction I/O (A+,A- , B+and B-)
The functionality of these terminals is the same as for the basic MAC motor. They can be
set up in 3 different configurations.
- Pulse inputs - for functional description please refer to
inputs, page 116
page 146
- Pulse outputs - for functional description please refer to
pulse outputs, page 117
- RS422 interface - for functional description please refer to
description, page
Important!:
Remember to configure "I/O type" as "Pulse Input" in MacTalk if none of the 4 terminals
A+, A-, B+ and B- is used (the multifunction I/O's). This must be done to avoid random
function of the motor since the multifunction I/O's are defined as "Serial data" as default.
• Status outputs (O1, O2, O+, and OCM)
The status outputs O1 and O2 (PNP outputs) indicate the actual status of the MAC
motor.
O1 This output functions as an "In Position" or "at velocity" output depending on
O2 This output is normally passive but if an unrecoverable error occurs, it will be
• RS485 Interface (A-, B+ and GND)
Serial balanced interface for connection to a PC or a controller. The protocol is sim-
ilar to the RS232 or USB interface, which means that all registers/parameters in the
motor can be monitored or changed. The RS485 is recommended for longer distanc-
es or in noisy environments.
• RS232 Interface (Rx, Tx and GND)
Serial unbalanced interface for connection to a PC or a controller. The protocol is
similar to the USB or RS485 interface, which means that all registers/parameters in
the motor can be monitored or changed. RS232 is not recommended for long dis-
tances (>10m).
The MAC motor uses "binary" communication protocol which makes it possible to ac-
cess all the internal registers. Please consult
