Detailed Product Description

Pulse Width Modulation DC Motor Control Drive

Instructions of MMT DC24DP10-35BL

.  Product performance

1. The mechanical characteristics of hardness, static error rate of 1%.
2. A wide speed-regulating range (0 - max).
3. A rapid dynamic response process.
4. Automatic and smooth transition process during acceleration or deceleration.
5. Better excavator characteristics, can limit overload current to set value current.
6. High reliability and compact structure, high performance-price ratio.

. Adjustment Instructions:

1. Current Setting/Limiting Adjustment: TORQUE

This potentiometer adjustment is intended for setting/limiting the max output current of the driving board according to the rated current of the motor. Through adjusting this potentiometer, the max output current of the driving board can be up to 120%~200% of the rated current.

2. Torque Compensation Adjustment: IR COMP

IR COMP potentiometer is used to keep the motor speed constant when they are working with different loads.

3. Soft Starting Time Adjustment: ACCEL

Through adjusting this potentiometer ACCEL, the upward slope from the starting speed to the preset speed can be defined (i.e. the time required to reach the preset speed, optionally between 010s). See Figure 1

4. Soft Stopping Time Adjustmentinner fixed: DECEL

Through adjusting this potentiometer DECEL, the downward slope from max speed to the minimum speed can be defined. (See Figure 2)

5. Adjustment of maximum output voltageMAX COMPupward inside the drive

Adjustment of the potentiometer can be make sure drivers highest output voltage, adjustment ran related range 12V-24V.

. Instructions of terminal blocks

1. DC  INAccess DC power source input terminal (Note: positive, negative wiring must be correct, otherwise they will be broken down.)    

2. OUT + Armature output (connected to motor armature)

3. Given signal inputPotentiometer and analog signal control mode See Figure 3

4. External enabling circuit block (INHIBIT)

Enabling circuitry connecting - the control by a "enabling circuitry" to stop and open control (running when closed and stop when disconnected). Connect Switch to the terminal INHIBIT. See figure 4. When the switch is closed, the motor starts, when the switch is off, the motor stopped sliding.
An Open Collector (NPN) can replace the switch to connect.

. Instructions of LED indicators:

1. L1: Power normal instructions (Green)
2. L2: over current / short circuit protection instructions (Red)
    AWhen the output current of driver over "TORQUE" current set value (see the fifth item in the adjustment    instructions of potentiometer), the light is on (whether the driver stops output, please refer to the Instructions on interpolation interface and plug-in selection
 Ways of reset: After troubleshooting, reset "INHIBIT" ports external enabling locking switch or reconnect drivers      power source.

BWhen the driver "+ OUT -" output terminal has the external short-circuit, the drivers will quickly stop exporting, at the same time light L2 over current / short circuit protection indicator.
Reasons of reset: After identify the reasons and troubleshooting, re-connect drivers power source.

3. L3: external enabling block state instructions (yellow)
  When the external enabling locking switch "INHIBIT" port disconnect, the indicator light on
  When the external enabling locking switch "INHIBIT" port connect, the indicator light off

CH1: Signal Isolators jack (three cores)    CH2: Rotation speed sensor jack (four cores)

. Over current protection mode options (inside of the drive)

Short needle to A- B options:

AShort access to short-needle A: The driver output current reaches the set value, the driver will be automatically restricted in the current settings (TORQUE set value) to achieve protection purposes of the motor current limit. See Figure 5

BShort access to B end of needle: The driver output current reaches the set value of 0.7 seconds, the driver will automatically stop output, and maintain the state. See Figure 6
