Page 4: Introduction
1 Introduction Thank you for selecting the Applied Motion Products STR3 step motor drive. We hope our commitment to performance, quality and economy will make a successful motion control project. The STR3 Step motor drive is a cost-effective, high performance drive. -
Page 5: Safety Instructions
920-0102 Rev. E STR3 Hardware Manual 01/25/2018 1.3 Safety Instructions Only qualified personnel should transport, assemble, install, operate, or maintain this equipment. Properly qualified personnel are persons who are familiar with the transport, assembly, installation, operation, and maintenance of motors, and who meet the appropriate qualifications for their jobs. -

• A small flat blade screwdriver for configuring the switches (included) 2.1 Mounting the Hardware As with any step motor, the STR3 must be mounted so as to provide maximum heat sinking and airflow. Keep enough space around the Step motor drive to allow for airflow. -
Page 7: Multiple Drives Sharing One Power Supply
920-0102 Rev. E STR3 Hardware Manual 01/25/2018 We recommend the following selection procedure: 1. If you plan to use only a few drives, get a power supply with at least twice “per phase” current rating of the step motor. Example: for a motor that’s rated for 2 A/phase use a 4A power supply. -

920-0102 Rev. E STR3 Hardware Manual 01/25/2018 3.1.1 Connect Main Power Supply If the power supply does not have a fuse on the output or some kind of short circuit current limiting device a fast acting fuse is required. A 3 Amp fast acting fuse should be installed in line with the “+” power supply lead. -

920-0102 Rev. E STR3 Hardware Manual 01/25/2018 3.1.4 EN Input The EN input enables or disables the drive Amplifier. It is an optically isolated input that accepts a 5 to 24 volt single-ended or differential signal. The maximum voltage that can be applied to the input is 28V. -
Page 12: Switch Selecting
3.2.1 Running Current The output current of the STR3 step motor drive is set by the SW1, SW2 and SW3 switches and can be changed as necessary. There are 8 settings available according to the ON/OFF combination of the switches. -
Page 13: Idle Current
01/25/2018 3.2.2 Idle Current The running current of the STR3 is automatically reduced whenever the motor isn’t moving. Setting the SW4 switch to ON maintains 50% of the running current. Setting this switch to OFF maintains 90% of the running current. This 90% setting is useful when a high holding torque is required. -
Page 14: Self Test
01/25/2018 3.2.4 Self Test A built-in self-test feature is available on the STR3 to check the physical operation of the motor. Setting switch SW9 to ON after the drive is powered up will cause the drive to perform a self test move of 2 revolutions both CW and CCW at 1rps. -

Page 21: Motor Heating
920-0102 Rev. E STR3 Hardware Manual 01/25/2018 6.4 Motor Heating Step motors convert electrical power from the driver into mechanical power to move a load. Because step motors are not per- fectly efficient, some of the electrical power turns into heat on its way through the motor. This heating is not so much depen- dent on the load being driven but rather the motor speed and power supply voltage. - Page 22 920-0102 Rev.E STR3 Hardware Manual 01/25/2018...
