Product Description

DH series servo driver
Fast | Intelligent | Accurate
The DH series programmable intelligent servo driver is a universal, high-performance, DC-powered, compact all-digital servo driver. It is mainly applied to the position, speed and torque control of linear (DDL), torque (DDR), voice coil, brushed and brushless servo motors. It can operate in three modes: stand-alone programmable control (Stand alone), external control, or distributed network control. It can support incremental encoders, analog sine and cosine encoders (Sin/Cos), resolvers, and digital Hall feedback.

7、Driver status indicator Light (AMP) | |
The red/green dual-color LED light tells us the status of the driver through color changes and whether it flashes or not. The possible situations are: | |
Green/Not flashing | The drive is OK and enabled |
Green/Slow flash | The drive is okay but not enabled. It can run after being enabled |
Green/Flash | When the positive or negative limit switch is effective, the motor will only move in the direction not prohibited by the limit switch |
Red/Fixed | Instantaneous fault. After the fault is eliminated, the amplifier needs to be restarted |
Red/Flashing | Lock the fault and restart the amplifier to resume operation |

2 | RXD | RS232 communication receiving terminal | |
3 | GND | Communication power supply ground | |
5 | TXD | RS232 communication sender |
9、SW driver CAN address dip switch | |
When the software setting selection is to use an external dip switch, the dip of this switch is valid. The switch encoding follows the sequence of BCD codes. It is valid when the dial is set to ON | |
The SW dip switch corresponds to the station number | |
SW Switch serial number | Corresponding station number |
1 | 1 |
2 | 2 |
3 | 4 |
4 | 8 |
For example, to set the station number to 3, switch 1 and 2 of the SW switch to ON and the others to off. 1+2=3. If you want to set the station number to 12, switch 3 and 4 of SW to ON, and set the rest to ooff. 4+8=12 |
