Operation
Getting started
The quickest way to get started with the SMD3, having completed wiring up according to the previous chapter is to install the SMD3 software on your PC (see section 6), power on the SMD3 and connect it with the USB lead to the PC. The SMD3 software provides an intuitive and easy way to configure and evaluate the features of the SMD3 described in the remainder of this section.
This section discusses the various operational modes and configuration options available. The SMD3 software provides easy access to these functions, as well as help text describing each. If communicating with the SMD3 directly, using a terminal program or your own software, see section 7 which lists the commands available.

Temperature sensor selection
AML motors can be supplied with either a K-Type thermocouple or PT100 RTD temperature sensor. Ensure the sensor is connected to the thermocouple (X4 - Thermocouple) or RTD (X3 – I/O, see 4.3.4) input, and make the appropriate selection. The temperature sensor select command [TSEL
] allows selection between thermocouple and RTD.
INFORMATION: The motor is disabled if the temperature sensor is misconnected, faulty or the temperature measurement exceeds 190 °C in order to protect the motor from possible damage to the insulation material.
Check that the motor temperature sensor selection matches that of your motor.

Clearing a fault
Faults may be cleared using the clear command [CLR], or by pulling the fault reset pin to the ‘GND’ pin on ‘X3 – I/O’.
The external enable fault is non-latching when in step direction mode; once the external enable state is restored, or the external enable setting is changed to false, normal operation will resume immediately without the need to clear it as described above.
