Section 1. Regenerative Drives

Most non-regenerave, variable speed, DC drives control current ow to a motor in one direcon. The direcon of current ow is the same direcon as the motor rotaon. Non-regenerave drives operate in Quadrant I, and also in Quadrant III if the drive is reversible (see Figure 1). Motors must stop before reversing direcon. Unless dynamic braking is used, non regenerave

drives cannot decelerate a

load faster than coasng to a lower speed.

Regenerative drives operate in two addional quadrants: Quadrant II and Quadrant IV. In these quadrants, motor torque is in the opposite direcon of motor rotaon.

This allows regenerave drives to reverse a motor without contractors or switches, to control an overhauling load, and to decelerate a load faster than it would to coast to a lower speed.

Heat Sinking

Models MMRG30U, MMRG30U-PCM, MMRG40U, and MMRG40U-PCM require an addional heat sink when the connuous armature current is above 5 amps. Use Minarik Drives heat sink kit part number 223-

0159. All other chassis drives have sucient heat sinking in their basic conguraon. Use a thermally conducve heat sink compound (such as Dow Corning® 340 Heat Sink Compound) between the chassis and the heat sink surface for opmum heat transfer.

• Drive components are sensitive to electrostatic discharge. Avoid direct contact with the circuit board. Hold the drive by the heat sink only.

• Protect the drive from dirt, moisture, and accidental contact.

• Provide sufficient room for access to the terminals and calibration trim pots.

• Mount the drive away from heat sources. Operate the drive within the specified ambient operating temperature range.

• Prevent loose connections by avoiding excessive vibration of the

drive.

• Mount the drive with its board in either a horizontal or vertical plane. Eight 0.19” (5 mm) wide slots in the chassis accept #8 pan head screws. Fasten either the large base or the narrow flange of the chassis to the subplate.

• The chassis should be earth grounded. Use a star washer beneath the head of at least one of the mounting screws to penetrate the anodized surface and to reach bare metal.

Shielding Guidelines

Under no circumstances should power and logic level leads be



As a general rule, Minarik Drives recommends shielding of all conductors. If it is not praccal to shield power conductors, it is recommended to shield all logic-level leads. If shielding of all logic-level leads is not praccal, the user should twist all logic leads with themselves to minimize induced noise.

It may be necessary to earth ground the shielded cable. If noise is produced by devices other than the drive, ground the shield at the drive end. If noise is generated by a device on the drive, ground the shield at the end away from the drive. Do not ground both ends of the shield.

If the drive connues to pick up noise aer grounding the shield, it may be necessary to add AC line ltering devices, or to mount the drive in a less noisy environment.

Logic wires from other input devices, such as moon controllers and PLL velocity controllers, must be separated from power lines in the same manner as the logic I/O on this drive.

Line Fusing

Chassis drives should be fused for protecon. Use fast acng fuses rated

for 250 VAC or higher and 150% of maximum armature current. Fuse HOT L1 only when the line voltage is 115 VAC. Fuse both L1 and L2 when the line fuse is 230 VAC. Table 1 lists the recommended fuse sizes.

Power Input

Connect the AC line power leads to terminals L1 and L2. Minarik Drives recommends the use of a single-throw, double-pole master power switch. The switch should be rated at a minimum of 250 volts and 200% of motor current. Refer to Figure 6 on page 13.

Motor

Drives supply motor armature voltage from A1 and A2 terminals. It is assumed throughout this manual that, when A1 is posive with respect to A2, the motor will rotate clockwise (CW) while looking at the output sha protruding from the front of the motor. If the motor does not spin in the desired direcon, remove power and reverse the A1 and A2 connecons.

Speed Adjust Potenometer

Use a 10K ohm, 1/4 W potenometer for speed control. The motor can operate in one direcon (unidireconal) or two direcons (bidireconal) depending on how the speed adjust potenometer is connected to the

drive.

For unidireconal operaon in the foward direcon, connect the speed adjust potenometer as shown in Figure 7(a).

For unidireconal operaon in the reverse direcon, connect the speed adjust potenometer as shown in Figure 7(b).

For bidireconal operaon, connect the speed adjust potenometer as shown in Figure 7(c). The motor does not operate when the potenometer is in the center posion. Turning the potenometer clockwise (CW) from the center posion causes the motor to rotate in the forward direcon, while turning the potenometer counterclockwise (CCW) causes rotaon in the reverse direcon.

Instead of using a speed adjust potenometer, the drive may be wired to follow an analog input voltage signal that is isolated from earth ground (Figure 5). Connect the signal common (–) S0. Connect the signal input (+) to S2. A potenometer can be used to scale the analog input voltage. An interface device, such as Minarik Drives model PCM4, may be used to scale and isolate an analog input voltage.

An analog input voltage range of -10 to 10 VDC is required to produce an armature voltage range of -90 to 90 VDC with 115 VAC line voltage or

Starng and Stopping Methods

Regenerave braking, coasng to a stop, or decelerang to minimum speed is recommended for frequent starts and stops.



Automac Restart Upon Power Restoraon

All drives automacally run to set speed when power is applied, the Start/Stop circuitry is closed, and the Run/Brake switch is opened.

Line Starng and Stopping

Line starng and stopping (applying and removing AC line voltage) is recommended for infrequent starng and stopping of a drive only. When AC line voltage is applied to the drive, the motor accelerates to the speed set by the speed adjust potenometer or analog signal. When AC line voltage is removed, the motor coasts to a stop.

Do not use any of these methods for emergency stopping. They

may not stop a drive that is malfunconing. Removing AC line power (both lines) is the only acceptable method for emergency stopping.

For this reason, Minarik Drives strongly recommends installing an emergency stop switch on both AC line inputs (see Figure 6 on page 13).

Frequent starng and stopping can produce high torque. This may cause damage to motors, especially gearmotors that are not properly sized for the applicaon.

Regenerave Brake to Zero Speed

Short the INHIBIT terminals to regeneravely brake the motor to zero speed (see Figure 12). The inhibit bypasses both the MIN SPD trim pot and the deceleraon rate set by the FWD ACC or REV ACC trim pots. Open the INHIBIT terminals to accelerate the motor to set speed.

Twist inhibit wires and separate them from power-carrying wires or sources of electrical noise. Use shielded cable if the inhibit wires are longer than 18 inches (46 cm). If shielded cable is used, ground only one end of the shield to earth ground. Do not ground both ends of the shield.

Minarik Drives oers two accessory plug harnesses for connecng to the INHIBIT terminals: part number 201-0024 [plug with 18 in. (46 cm) leads]; and part number 201-0079 [plug with 36 in. (91 cm) leads].

Regenerave Decel to Zero Speed

The Run/Stop switch shown in Figure 13 may be used to decelerate a motor to a stop. Closing the switch between S0 and S2 decelerates the motor from a set speed to a stop at a deceleraon rate determined by the ACC-DEC trim pot. Set the switch to the Run posion to accelerate the motor to set speed. Figure 13 shows the Run/Stop switch with a potenometer wired for bidireconal mode. For other possible wiring setups, see pages 14 and 30.

Maximum Speed (MAX SPEED)

The MAX SPD seng determines the maximum motor speed when the speed adjust potenometer or input voltage signal is set for maximum speed.

To calibrate MAX SPD:

1. Set the MAX SPD trim pot full CCW.

2. Set the speed adjust potentiometer or input voltage signal for maximum speed.

3. Adjust MAX SPD until the desired maximum speed is reached.

Acceleraon and Deceleraon (ACC-DEC)

The ACC-DEC trim pot seng determines the me the motor takes to accelerate to a higher speed or decelerate to a lower speed in the forward or reverse direcons, within the limits of available torque. Turn the ACC-DEC trim pot CW to increase the acceleration and deceleration time or CCW to decrease the acceleration and deceleration time. The ACC-DEC seng is factory set for its fastest forward acceleraon and deceleraon rate (full CCW).

IR Compensaon (IR COMP)

The IR COMP seng determines the degree to which motor speed is held constant as the motor load changes.

Use the following procedure to recalibrate the IR COMP seng:

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

2. Increase the speed adjust potentiometer or input voltage signal until the motor runs at midspeed without load (for example, 900 RPM for an 1800 RPM motor). A handheld 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 trim pot until the motor runs at the speed measured in step 2. If the motor oscillates (overcompensation), the IR COMP trim pot may be set too high (CW). Turn the IR COMP trim pot CCW to stabilize the motor.

5. Unload the motor.

See Figure 14 on page 29 for recommended IR COMP sengs.

Direcon Switch

For a Forward/Reverse switch, use a single-pole, two-posion switch with a single speed adjust potenometer to regeneravely reverse the motor (Figure 15). If a Forward/Stop/Reverse switch is desired, use a single-pole, three-posion switch (Figure 16). The MIN SPD seng is in eect for either direcon.

Leader-Follower Applicaon

In this applicaon, use a PCM4 to monitor the speed of the leader motor (Figure 24). The PCM4 isolates the leader motor from the follower drive, and outputs a voltage proporonal to the leader motor armature voltage. The follower drive uses this voltage reference to set the speed of the follower motor. An oponal rao potenometer may be used to scale the PCM4 output voltage.
