Pin Description:
VCC : Power +
GND : Power supply -
M+ : Motor +
M- : Motor -
GND : Trigger signal -
K1 : Forward input control
K2 : Reverse input control
S1 : Forward limit signal
S2 : Reverse limit signal
This module has 4 signal input terminals, ``K1``, ``K2``, ``S1``, ``S2``, K1 is the forward signal input, K2 is the reverse signal input, S2 is the forward limit signal input, and S2 is the reverse limit signal input. Signal input source can choose micro switch, induction, infrared, metal, remote control and other modules, also can be controlled by single-chip computer.
Operating Modes:
Mode 0 (default):
Self-locking mode, the signal only needs to be triggered once, the module self-locking has been running.
- Positive rotation process encounters a reversal signal, immediately stop 0.3 seconds after entering the reversal.
- limit signal priority, encounter positive rotation immediately stop positive rotation limit signal.
- Forward rotation cannot be started when there is a forward rotation limit signal, and the same is true for reverse rotation.
- forward and reverse signals are valid at low level, i.e. a short 0V level (negative power supply) will start.
- The limit signal is normally open; (If the SW1 switch is closed or connected to low level, forward rotation cannot be started.)
-Only one limit signal is valid at a time, for example, the motor rotation cannot be stopped by inputting two limit signals at the same time when reversing.
Mode 1:
The auto-start version of mode 0 adds a power-on auto-start function to mode 0, which means that positive rotation is automatically started every time the module is powered on. This version is more suitable as a motion module between two points, and the module works automatically when power is applied.
Mode 2:
Instantaneous mode. When there is a forward rotation signal, the motor turns forward; when there is a reverse rotation signal, the motor reverses; when there is no forward rotation signal and no reverse rotation signal, the motor stops; when in forward rotation, if there is a forward rotation limit, it stops forward rotation; during rotation, if there is a reverse rotation limit signal, it stops reverse rotation. Removing the two limit signals will not resume rotation, and the rotation signal needs to be input again to start forward and reverse rotation.
Mode 3:
Level drive mode, similar in function to H-bridge, operates according to the following logic.
When there is a forward rotation signal and no signal from the forward rotation limit, forward rotation; when there is a reverse signal and no signal from the reverse limit, reverse rotation; this version is pure logic type, suitable for microcontroller signal input. Pay attention to the positive turn priority, i.e. positive turn is the condition that both positive and negative turn inputs meet.
Pay attention to the real-time nature of the shutdown. For example, when there is a signal at the forward and reverse input terminals at the same time, it is positive turn. At this time, if the forward rotation signal is removed and the reverse rotation signal is retained, the rotation is reversed. The motor rotation time limit input is invalid, and the motor cannot stop.
Mode 4:
Start/Stop mode, the function is the same as mode 0, only the following function details are different.
If positive rotation has been started, input the positive rotation signal again to stop immediately; if reverse rotation has been started, input the reverse rotation signal again to stop immediately. For example: there is a forward signal >>> immediately forward; then input forward signal >>> immediately stop forward. The reverse is also the same.
Mode 5:
The function is the same as mode 0, except that the difference of limit signal is as follows.
The limit signal is only valid for the current time (frontier valid).
For example, after starting forward rotation, it stops when it meets the forward rotation limit signal. After stopping, although still input the positive rotation limit signal, but at this time input the positive rotation signal can still start positive rotation. This specification is usually used when the one-way start and end points are on the same motion circle, e.g. press once for one revolution and again for one revolution.
Mode 6:
One key switch mode, function as mode 0, only the start mode is different, as follows.
Positive signal input, positive rotation after triggering, reverse rotation after triggering again, and invalid reverse signal input. Input positive signal once to start positive rotation, and stop positive rotation when there is a signal at the positive rotation limit; input positive signal again to start reverse rotation, and stop reverse rotation when there is a signal at the reverse rotation limit.
Mode 7:
Forward rotation when there is a forward signal input, reverse rotation when there is no signal, reverse signal input is invalid and cannot be input with other signals. During forward rotation, if there is a signal of forward rotation limit, forward rotation stops; when reversing, if there is a signal of reversing limit, reversing stops. Only one limit signal is valid at a time.
For example, inputting two limit signals at the same time during reverse rotation can not stop the motor rotation.
Mode 8:
Self-locking-limit normally closed mode, only the difference of position signal, other functions are the same as mode 0. Limit signal is normally closed (e.g. when there is no signal input for forward limit, forward rotation cannot be started, only input forward limit signal can start forward rotation).
Power Requirements:
DC motor governor input should be DC power supply. Power supply can be used but not limited to the following: switching power supply, DC output transformer, lead-acid batteries, lithium batteries, solar batteries, etc. Power supply connection lines are connected to the ``VIN`` and ``GND`` terminals, the positive and negative polarity of the power supply can not be reversed. The supply voltage range is DC 11-15V (12V version), and can work normally between DC 22-26V (24V version); DC power supply requires power ¡Ã motor power × 3.
Motor Requirements:
IO56D02 is a DC motor controller, and the application motor should be a brushed DC motor. Connect the motor connection wires to the ``Motor+`` and ``Motor-`` terminals respectively. Motor power requirement: 24V DC motor rated power is less than 100W, limit is 200W; 12V DC motor rated power is less than 50W, limit is 100W.
