2.5 Test a drive at the playground
2.5.1 Prerequisites
The servo drive is connected to power supply, motor, position sensor and to a computer.
OBLAC Drives is installed, running and established a connection to the servo drive.
The latest firmware is installed on the drive.
All basic configuration parameters of the motor and sensor are copied from their datasheets to the drive
configuration.
The position sensor provides plausible data, the commutation offset was found.
was performed successfully.
2.5.2 Applying torque to a motor
If all the prerequisites ar met, the motor can be tested.
1. Go to OBLAC Drives.
2. Switch to the Playground section from the top menu.
3. Select “TORQUE CONTROL”.
4. Use the slider or the buttons to enter a reference torque.
Important
Applying a constant torque means that the motor shaft will start moving and not stop before you
manually set it back to a lower value. If anything is attached to your motor shaft (e.g. robotic
manipulator), make sure there are no mechanical limits to be exceeded or anything might be hit.
Torque is given in the unit per thousands of rated torque. So, if the motor’s datasheet specifies
T_rated = 0.5 Nm and you entered the corresponding 500 mNm into your configuration, setting the
torque setpoint to 100 will lead to:
100 * 1/1000 * 0.5 Nm = 0.05 Nm
Usually, a value between 50 and 300 should be sufficient to make any motor start rotating -
regardless of its absolute size and rated torque
The motor should start rotating now and you should be able to observe the motion in OBLAC Drives.
