4Q Braking-Reversible, PWM series DC Drive

MMT-DC24RT100BL

FEATURES:

DC-4Q Braking-Reversible, PWM series DC Drive, has quickly dynamic response, smooth operating, works well and perfect functions.

PULSE WIDTH MODULATION

Motor runs quieter, with greater efficiency and less maintenance, longer life.

FOUR QUADRANT REGENERATIVE OPERATION

REGENERATIVE BRAKING

   No contactors required. No electromechanical components to overheat or wear out.

ENABLE / BRAKE / DIRECTION TERMINALS

   Choose a function by simply opening or closing a dry contact or through an open collector transistor.

STATUS LEDs

Power and Fault LEDs provide a visual status of the drive.

Forward and reverse can be set separately

Output current can be set

Braking current can be set

Torque compensation function

Standard analog control mode:

   Analog:0-5V or potentiometer

OVER TEMPERATURE PROTECTION

   Drive will fold the output power back to prevent from overheating. Drive will fault if it still remains too hot.

Installation

1. Mount drive in a vertical plane. If mounted in horizontally add matching power accordingly.

2. Wire a power fast input fuse between the power supply and power input terminal. The fuse should be rated at 150% of input voltage and 150 - 200% of maximum motor name­plate current.

3. Ensure correct polarity.   See diagram 1.

4. Drive components are extremely sensitive to the , note the influence from the .

5. Protect the drive from dirt, moisture, and accidental contact. If not please take suitable protection measures

6. Mount the drive away from other heat sources, make sure there is enough thermal space, if not please take forced draft ventilation measures. Operate the drive within the specified ambient operat­ing temperature range.

7. Avoid mounting to vibration equipment, prevent loose connections by avoiding excessive vibration of the drive.

8. Mount drive with its heat sink in a vertical plane. If heat sink is mounted horizontally then derate the drives output power.

9. Dont put the input wire and output wire together, make the function control wire far away from input wire.

10. All the function wire are screening wire avoiding interference.

11. Use the suitable tools for installation and testing.

Speed adjust potentiometer

1. Enable (EN):

2. Brake (BRAKE)

3. Direction (DIR)

4. Control mode for reference:

1. ACCEL (ACCELERATION)

2. DECEL (DECELERATION)

3. MIN SPD (MINIMUM SPEED)

4. REV MAX SP (REVERSE DIRECTION MAX SPEED)

5. FWD MAX SP (FORWARD DIRECTION MAX SPEED)

6. REGEN CL (REGENERATIVE CURRENT LIMIT)

7. MOTOR CURRENT LIMIT (MOTOR CL)

8. IR COMPENSATION (IR COMP)

Use the following procedure to recalibrate the IR COMP setting:

1. Set the IR COMP trimpot to minimum (full CCW).

2. Rotate the speed adjust potentiometer until the motor runs at midspeed without load (for example, 900 RPM for an 1800 RPM motor). A hand held tachometer may be used to measure motor speed.

3. Load the motor armature to its full load armature current rating. The motor should slow down.

4. While keeping the load on the motor, rotate the IR COMP trimpot until the motor runs at the speed no-load 900rpm.

5. Unload the motor.

BEFORE APPLING POWER

1. Verify battery pack connections to the drive. Check for proper polarity. Incorrect polarity will damage the drive. Check the the input power is suitable rang.

2. Verify that no foreign conductive material is present on the printed circuit board. Protect the drive from dirt, moisture, and accidental contact.

3. Check the surrounding connecting line is correct, ensure that there is no short-circuit and earthing connections, (the correct way of wiring see Figure 1)

4. The external speed potentiometer to determine the minimum position (Given signal is 0 state)
