Supply Voltage
Drive internal switching power supply design ensures that you can adapt to a wide voltage range, the user can choose according to their own situation between 10V to 40VDC. Generally the higher rated supply voltage help to improve high-speed torque motor, but it will increase the drive's loss and temperature rise.
Output current selection
The maximum output current drive is 3A / phase (peak), the drive panel by six DIP switches can be combined in the first three out of eight 5,6,7 state, corresponding to eight output current from 0.9A to 3A to cater for different motors.
Select subdivision
The driver can provide full step, half-step improvement, four segments, eight segments, 16 segments, 32 segments, 64 segments and 128 segments of eight operating modes, using the drive panel DIP switches of the first six 1,2,3 three different states can be combined (see breakdown mode selection table). Description: white box panel screen printing on the actual location of the corresponding switch.
Semi-automatic current
If the host controller did not issue a pulse signal within half a second, the drive will automatically enter power-saving semi-current operating mode, the phase current motor winding will be reduced to half of the set value, in this state, the motor and drive power consumption can be reduced, but the motor output torque is also correspondingly reduced. When the arrival of the next pulse drive output current rating of automatic recovery.
Wrong phase protection
When the two-phase motor and drive is connected, the user can easily pick the wrong phase, which seriously damage the drive. The driver of the wrong phase protection circuit design. Even if the user pick the wrong phase, the drive will not be damaged, but the motor will not run properly, mainly in output is minimal. If this happens, you should check the motor wiring is correct.
About the heat
Operating temperature is too high is the source of most of the line failures, effective cooling is particularly important for improving the reliability and operating life. Recommended to drive tightly fixed on the user's metal chassis, cooling assistance through the chassis backplane. Able to do so also in contact with the surface of a thermally conductive material, such as adding grease. If additional cooling fan, the temperature rise of the drive will be greatly reduced.
