• 4-20mA Analogue input (AIN+ and AIN-)
The analogue input is read by the motor and will typically be used with the motor set
in "Analogue to position mode". In this configuration the motor position will follow
the analogue input proportional in a user defined working range.
The analogue input has a resolution of 16 bit corresponding to the rang 0 to 20mA
divided into 65536 steps. The input is galvanic isolated from all other terminals and
circuits.
• 4-20mA Analogue output (AOUT+ and AOUT-)
The analogue output is monitoring the actual position when the motor is set in "An-
alogue to position mode". In this configuration the output value will be from 4 to
20mA proportional to the actual motor position in a user defined working range.
The analogue output has a resolution of 16 bit corresponding to the rang 4 to 20mA
divided into 65536 steps. The output is galvanic isolated from all other terminals and
circuits.
• RS485 Interface (A-, B+ and IGND)
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 IGND)
Serial unbalanced interface for connection to a PC or a controller. All registers/pa-
rameters in the motor can be monitored or changed. RS232 is not recommended for
long distances (>10m).
The MAC motor uses "binary" communication protocol which makes it possible to ac-
cess all the internal registers. Please consult MacTalk communication, page 283 for further
details.
