Frequent starting and stopping can produce high torque. This may cause damage to motors, especially gearmotors that are not properly sized for the application. Dynamic braking may be used to rapidly stop a motor Figure 18, page For the dynamic brake resistor, use a 40 watt minimum, high power, wirewound resistor. Sizing the dynamic brake resistor depends on load minarik variable speed scr, motor voltage, and braking time. Use a lower-value, higher-wattage dynamic brake resistor to stop a motor more rapidly.
Refer to Table 4 page 40 for recommended dynamic brake resistor sizes. Replace the dynamic brake with gauge wire. Dynamic Brake Connection. When possible, disconnect the voltage input from the drive before adjusting the trimpots. If the trimpots must be adjusted with power applied, use insulated minarik variable speed scr and the appropriate personal protection equipment. MMseries drives have user-adjustable trimpots. Each drive is factory calibrated to its maximum current rating.
Readjust the calibration trimpot settings to accommodate lower current rated motors. Use a non-metallic screwdriver for calibration.
Each trimpot is identified on the printed circuit board. It is factory set for zero speed. It is factory set for maximum rated motor speed.
Set the speed adjust potentiometer or voltage input signal for maximum forward speed. Continuous operation beyond this rating may damage the motor. If minarik variable speed scr intend to operate beyond the rating, contact your Minarik representative for minarik variable speed scr. With the power disconnected from the drive, connect a DC ammeter in series with the armature. Set the speed adjust potentiometer or voltage reference signal to maximum speed full CW. Trusted seller, fast shipping, and easy returns. Advanced Search parts kvalinc. Zener diode Z1 provides a threshold to prevent erroneous firing turning on of the SCR 32 due to small fluctuations of the armature voltage of the motor 1. In this condition, the safety module 30 is inactive, and the speed control circuit 10 and the motor 1 operate normally.
Load the motor armature to its full load armature current rating.
Part # 63838
These instructions must be followed minarik variable speed scr safe and reliable operation. Power input For chassis drives, connect the AC line power leads to terminals L1 and L2, or to a double-throw, double-pole master power switch recommended as shown in Figure 7, page Installation 15 Figure 7.
Minarik drives supply motor voltage from A1 and A2 terminals. Figure 8. Installation 17Voltage follower MMC only Instead of using a speed adjust potentiometer, the drive may bewired to follow an analog input voltage signal that is isolated fromearth ground Figure 9. The minarik variable speed scr of this signal is 0 - 6 VDC. Connect the signal common — to S1. Make no connection to S3.
A potentiometer can be used toscale the analog input voltage. To achieve isolation, use aninterface device such as Minarik model PCM4 to scale the analoginput voltage.
