Apply power to the drive. 2.2 Mounting the Hardware As with any step motor, the STM23C must be mounted so as to provide maximum heat sinking and airflow. Keep enough space around the Integrated Motor to allow for airflow. •... -
Page 8: Choosing A Power Supply
2.3.1 Voltage The STM23C is designed to give optimum performance between 24 and 48 Volts DC. Choosing the voltage depends on the performance needed and motor/drive heating that is acceptable and/ or does not cause a drive over-temperature. Higher voltages will give higher speed performance but will cause the STM23C to produce higher temperatures. -
Page 9: Current
STM23C User Manual 2.3.2 Current The maximum supply currents required by the STM23C are shown in the charts below at different power supply voltage inputs. The STM23C power supply current is lower than the winding currents because it uses switching amplifiers to convert a high voltage and low current into lower voltage and higher current. - Page 10 STM23C User Manual STM23-2 48V Power Supply Current 3 .0 0 2 .5 0 2 .0 0 1 .5 0 Torque 1 .0 0 S upply 0 .5 0 C urrent 0 .0 0 S upply C urrent Speed (RPS)

Connect the power supply “+” terminal to the drive “+” terminal and the power supply “-” terminal to the drive “-” terminal using 16 to 20-gauge wire. The STM23C contains an internal fuse connected to the “+” terminal. This fuse is not user replaceable. If a user serviceable fuse is desired, install a 4 amp fast acting fuse in line with the “+”... -
Page 13: Connecting The Stm23C Communications
Locate the STM23C within 2.5 meters of the PC. Plug the large end (DB9 connector) of the cable into the serial port of the PC. Plug the 3-pin spring clamp connector into the appropriate connector on the STM23C. Secure the cable to the PC with the screws on the DB9 connector. -

Page 16: Programmable Output
STM23C User Manual 3.3.4 Programmable Output The STM23C drives feature one optically isolated digital output. This output can be programmed to automatically control a motor brake, to signal a fault condition, to indicate when the motor is moving or to provide an output frequency proportional to motor speed (tach signal). Or the output can be turned on and off by program instructions like Set Output (SO). - Page 17 STM23C STM23C User Manual OUT- Connecting a Sourcing Output again 5 – 24 volt Power Supply relay OUT+ STM23C 1N4935 suppression diode OUT- Driving a Relay Rev. 1.0 2010/11/03...

Page 18: Configuration
STM23C User Manual 4 Configuration ST Configurator is the PC based software application that is used to configure the STM23C. It can also upload, save, or open any saved STM23C configurations. Motor configuration for the STM23C is rather simple as most parameters are fixed. Because it is an integrated motor/driver, the configuration generally has only three elements - the I/O, CANopen settings, and the Motor. -
Page 19: Help Menu
PC serial port. If the box does not list the correct model after the STM23C is powered up, please check the wired connections (including the power supply and communications connections.) If the STM23C is intentionally not connected, the model and revision can be chosen from the drop down list on the upper right. -
Page 20: Motor (Integrated Motor)
In the Integrated Motor dialog box, operational parameters are defined and configured. Motor Specs cannot be modified as they are fixed according to the STM23C model selected in the Drive selection box. 4.3.1 Running Current This value is set by default to a current level that gives good performance at constant speed but lower than the maximum current to allow the integrated motor to operate at a lower temperature. -
Page 21: Idle Current Delay
STM23C User Manual 4.3.4 Idle Current Delay The Idle Current Delay is the amount of time between when the motor stops and the current is reduced to the Idle Current value. It is recommended to allow a little time for the motor to settle out before the current is reduced. -

(SO), Feed to Length and Set Output (FO), Immediate High Output (IH), and Immediate Low Output (IL) commands. 4.5 Encoder (optional) The Encoder operation on the STM23C is programmed using ST Configurator. The number of counts/turn cannot be changed as it indicates the count of the Encoder installed at the time of purchase. -
Page 24: Canopen
4.6 CANopen Each node on a CANopen network must have a unique Node ID. On the STM23C, this is set using both the ST Configurator software and the sixteen position switch on the front of the drive. CANopen Node IDs are seven bits long, with a range of 1 - 127, or 0x01 - 0x7F in hexadecimal notation. -
Page 25: Simple Operation
STM23C User Manual 5 Simple Operation After the STM23C is wired and the configuration is downloaded, ST Configurator can be used for several simple operations. These features are accessible through the drop down list in the Drive menu. Self Test This feature will instruct the motor to rotate a half revolution in alternating directions at a low speed to verify that the motor is operational. - Page 26 STM23C User Manual The commands and their responses should appear as shown in the Host Terminal window below: Every command should have a drive response of “%” which means the command was received and executed. With this example the motor will move one revolution at 10 rev/sec.

Page 34: Drive/Motor Heating
STM23C User Manual 7.5 Drive/Motor Heating Step motors convert electrical power from the driver into mechanical power to move a load. Because step motors are not 100% efficient, some of the electrical power turns into heat as it passes through the motor. The amount of heating is not so much dependent on the load being driven as on the motor speed and power supply voltage. - Page 35 STM23C User Manual STM23X-3 Max Duty Cycle vs Speed 12V D uty C y c le 5 Amps @ Ambient of 40°C 24V D uty C y c le 162 x 162 x 6 (mm) Aluminum Plate 48V D uty C y c le...
