Operating Instructions
Set the number of segments
By the 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
Output current setting
The SW1-SW3 three DIP switches to set the driver output current , the output current total of eight files.
Automatic half current function
Users 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
Name
Explanation
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 +
When the input pulse + direction for direction 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 stepping
Pulse is not responding. When not required for this function, you can enable signal end vacant .
ENA-
Motor Interface
Positive and negative terminals B + and B- phase winding connected to the stepper motor B ; A + and A- negative terminal connected to the A-phase stepper motor winding. When the A, B two-phase windings any set of positive and negative exchange , can reverse the motor direction .
Power Interface
DC power supply, operating voltage range of suggestions for 20-48VDC, Power greater than 100W.
Indicator
Green LED power indicator is when the drive is powered , the LED is 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
1
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
3US556 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 , 3US556 dedicated communication cable must be used to communicate with the computer , self- wiring can easily result in errors caused by wiring burned Communications interface circuitry. 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
The dimensions of the drive : 118 × 73 × 34mm, installation pitch of 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 .
