It is recommended to use side installation, better heat dissipation effect, when the design and installation size, pay attention to the terminal size and wiring!

4. Strengthen heat dissipation

1)The reliable operating temperature of the drive is usually within 50℃ and the motor is within 80℃;

2)It is recommended to choose the automatic half-flow mode, that is, when the motor stops, the current automatically reduces by half, to reduce the heat of the motor and the drive;

3)When installing the drive, use the side installation and form strong air convection on the drive bottom; if necessary, install the fan near the drive to form air convection, assist the drive heat dissipation, and ensure that the drive works within a reliable operating temperature range.

2. Control the signal interface circuit

Fig. 2 Input interface circuit

The differential signal circuit is used for the HS57 drive control signal end, which can be applied to the differential signal, one-end coYin and co-Yang interfaces, with built-in high-speed photoelectric coupler and strong interference resistance in cases of bad environment.A schematic diagram of the interface circuit is shown in Figure 

▶ Note: The HS57 is a 5V-24V universal drive, so no serial resistance is required;

3. Control signal timing diagram

To avoid some misaction and deviations, P LS, DIR and ENA shall meet certain requirements as shown in the following figure:

FIG. 3 A control signal timing diagram

explanatory note:

1)The t1: ENA (enabling signal) shall be DIR at least 5ms in advance to be high.ENA + and ENA-suspension are generally recommended.

2)The t2: DIR at least early P LS decreases along 5s determines its state high or low.

3)The t3: Pulse width is not less than 2.5s.

4)The t4: Low level width is not less than 2.5s.

4. Control the signal mode setting

Pulse trigger edge selection: The pulse up edge or drop edge trigger can be set through the PC software.

5. Connection requirements

1)In order to prevent the interference of the drive, it is recommended to adopt the control signal shield cable, and the shield layer is short connected to the ground wire. Except for special requirements, the single end of the shield wire of the control signal cable is grounded: one end of the upper machine of the shield wire is grounded, and one end of the shield wire is suspended.Only the same ground in the same machine, if not the real grounding wire, may interfere seriously, when the shielding layer is not connected.

2)Pulse and direction signal line and the motor line are not allowed to be bandaged side by side, it is best to be separated by at least 10cm, otherwise the motor noise can easily interfere with the pulse direction signal to cause inaccurate motor positioning, system instability and other faults.

3)If one power supply is for multiple drives, a parallel connection should be taken at the power supply to one first to one chain is not allowed.

4)The strong electric terminal of the live unplug drive is strictly prohibited. When the charged motor stops, there will still be a large current flowing through the coil. The live unplug terminal will lead to a huge instantaneous inductive electric drive to burn out the drive.

5)It is not prohibited to tin the wire head to the terminal, otherwise the terminal may be overheated due to large contact resistance.

6)The wiring head shall not be exposed to the terminal to prevent accidental short circuit.

Dialup switch function setting

The HS57 drive uses a 10-bit dial-up switch, and SW1-SW4 is used for ALM, PEND output configuration setting, algorithm selection, maximum peak current setting, and direction selection; SW5-SW8 is used for subdivision setting; and SW9-SW10 is used for working mode selection.Details are described as follows:

Power supply selection

The power supply voltage can work normally between the specified range. The HS57 drive should preferably use non-stable DC power supply, or transformer voltage reduction + bridge rectification + capacitance filter.However, it should be noted that the rectified voltage ripple peak shall not exceed the specified maximum voltage.It is recommended that users use DC voltage below the maximum voltage to avoid grid fluctuations exceeding the operating range of the drive voltage.

If the voltage stable switch power supply is used, the output current range of the switch power supply should be set to the maximum.

▶ pay attention to:

1)Pay attention to the positive and negative power supply do not reverse connect;

2)It is best to use a non-stable type of DC power supply;

3)When using the non-stable voltage power supply, the power supply current output capacity should be greater than 60% of the set current of the drive;

4)When using a non-stable voltage switch power supply, the output current of the power supply shall be greater than or equal to the operating current of the drive;

5)To reduce costs, two or three drives can share one power supply, but should ensure sufficient power.


defencive function

1. short-circuit protection

In case of a alternate short circuit and an overflow inside the drive, the drive red light flashes once and flashes repeatedly in a cycle of 3 seconds.At this point, the fault must be eliminated and reset again.

2. overvoltage crowbar

When the input voltage is higher than the DC50V, the drive red light flashes twice and flashes repeatedly in a 3-second cycle.The fault must be eliminated and reset again.

3. undervoltage protection

When the input voltage is below the DC20V, the drive red light flashes 3 times and repeatedly in a 3-second cycle.The fault must be eliminated and reset again.

4. Lack of phase protection

When the current is initial, when the motor is phase, the driver red light flashes 5 times and flashes repeatedly in a cycle of 3 seconds.The fault must be eliminated and reset again.

5. Excess alarm signal

When an differential alarm occurs, the red light of the drive will remain on.The fault must be eliminated and reset again.
