♦♦ Drive Function
Drive Function Operating Instructions
Subdivision set by SW5-SW8 four DIP switches to set the number of micro-step breakdown of the drive , which has 15 stalls micro-step . When users set the micro-step , you should stop the drive to run. See detailed breakdown set the table .
RS232 communication settings subdivision range 1-65535
The output current is set by SW1-SW3 three DIP switches to set the driver output current , the output current total of eight files.
Automatic half current function the user can set the drive through SW4 automatic half current function. Quiescent current is set to half off said dynamic current , on said quiescent current and dynamic current is the same . General applications should SW4 is set to off, so that the motor and the drive to reduce fever , increased reliability . After a burst of about 0.4 seconds to stop automatically reduced to about half of the current (60 % of the actual value ) , reduced to 36% of the theoretical heat .
Signal Interface Description
PUL + pulse control signal: pulse rising edge ; HIGH 45V, low level 0 ~ 0.5V.
For reliable response to the pulse signal , the pulse width should be greater than 1.2μs. Series resistance as required when using +12 V or +24 V.
PUL-
DIR + pulse + direction when the input mode when , for the direction of the signal: high / low signal , in order to ensure reliable motor commutation , the direction of the signal should be at least 5μs pulse signal is created. The initial direction of the wiring of the motor on the motor , interchange any phase windings ( eg A +, A- exchange ) can change the initial operation of the motor driving , the DIR- HIGH 4 ~ 5V, the low level 0 ~ 0.5V. Series resistance as required when using +12 V or +24 V.
When the double- pulse input mode for reverse pulse signal: its characteristics PUL +, PUL- identical
When the input mode for the encoder to follow, as the B -phase pulse signal : its characteristics PUL +, PUL- identical
DIR-
ENA + Enable signal : This input signal is used to enable or disable . ENA + pick +5 V, ENA- connected low ( or internal optocoupler conduction ) , the drive current of the motor will cut off all phases of the motor is in a free state, then step pulse is not responding. When not required for this function, you can enable signal end vacant .
ENA-
Positive and negative terminals B + and B- B -phase stepping motor connected windings ; positive and negative ends of the motor interfaces connected to A + and A- A phase stepper motor windings . When the A, B two-phase windings any set of positive and negative exchange , can reverse the motor direction .
Power connector DC power supply operating voltage range is recommended for the 20-48VDC, Power greater than 100W.
Green LED indicator for the power indicator light, when the drive powered on, the LED lit ; drive off the power when the LED is off. Red LED fault indicator , when a fault occurs , the indicator based on the type of fault to 0.2 seconds cycle set number of flashes and then continue to repeat at 1 -second intervals with 0.2 seconds to set the number of circulating flashing . Until the fault is cleared by the user , the red LED is off . The number of flashes corresponds to the type of fault in the following table :
The number of flashes fault type
An overcurrent
2 power supply voltage is too low
3 Power supply voltage is too high
4 phase error
5 parameter tuning and learning process of identification error
Other hardware failure, for manufacturers to identify the specific type of
Communication port US556 achieve set number of users subdivision and change the setting pulse input mode , half- time and other parameters of the flow through the RS232 interface to communicate with the computer , US556 dedicated communication cable must be used to communicate with the computer , self- wiring can easily result in errors caused by wiring burned communication interface circuit . Drive factory parameters to meet the requirements of most users , dedicated communication cables as an alternative to buy parts for the user , there is a need to change the parameters of the user can contact the drive manufacturer.
Installation instructions for the drive Dimensions : 118 × 73 × 34mm, mounting hole spacing is 112mm. Both horizontal and vertical installation, we recommend the use of vertical installation . When installed, it should be close to the metal cabinet to facilitate cooling .

♦ parameter self-tuning function
If SW8 within one second of the round struck once , the drive motor parameters can be automatically learn and PID parameter tuning . After adjusting the red LED will light indicating the completion of what ; pick or updates in the new re-learn motor , power supply voltage conditions change parameters , otherwise, the motor may run is not satisfactory or even not running. Parameter learning phase, pulse input , and direction of change will be invalid.
After completion of study parameters to restore the previous state of SW8 .
