product in installed. (Labour safety and sanitary regulations, electricalequipment technical standard, etc)
● Operate the motor driver within its intended design and specifications to
avoid electrical shock, injury, fire, or damage to the equipment.
● Do not disassemble, repair nor modify the product (for which we do not
warrant) It might cause electrical shock, injury or fire.
● Separately set the circuitry to monitor the important input and/or output signal
status, which might cause accident, because the signal may stay ON or OFF
in case of the CB-016 driver card failure.
● Be sure to shut off the power before inserting or removing any connector. Do
not wire connector left in the CB-016 driver card.
● Do not drop, give external impact nor pressure to the CB-016 driver card. If
that happens, do not reuse it.
● Make sure all the connecters are properly engaged with wiring cables.
● Make sure the conveyor frame and control box where the CB-016 driver card
is mounted are grounded.
● Do not switch on or off the relay or contactor in close proximity to power orsignal lines, or the CB-016 driver card as the generated noise could cause
malfunction.
● Be sure to inject power or input signal for 15 milli-seconds or over to ensure
the proper reaction.
● Use the MDR with built-in brake option (BR) along with CB-016 driver card
〔ＢN6〕〔ＢＰ6〕 if holding effect is needed.
● Do not pull by force during operation. It causes the CB-016 driver card to
malfanction.
● Do not force the MDR to turn. It may cause of damage to the driver card or
shorten its life cycle.
<Described below are the precautions for using this product at freezing
temperature along with MDR having LT option:>● Connenctor may harden with low temperature. Do not insert and pull it byforce.
● Mount this product to the place where MDR can be properly connectedwithout cable loose, extreme bend or pull, or move.
● MDR speed may not reach immediately to the set speed if it is left long hours

in 0 ℃ or below. In addition, the starting current may get larger to activate
thermister, or under voltage error may be resulted. Therefore , warm up
operation is recommended before formal use.
● Be careful for condensation or freeze in case the product is used in varying
temperature particularly between below and above 0℃. If condensation is
generated, do not use the product until it is completely removed. Use of the
product having condensation may result in malfunction or electrical accident.

2 Power
24VDC battery or switching power (24VDC 5A) or
smoothed and rectified power (≦10% ripple)* Use stable power supply with 5A or over. The Power supply should not be affected bypeak current 20A for 1msec.

① Wire 24VDC and 0V to the Power Connector CN 1(2P)＊Connector current capacity is 10A. Avoid
wiring causing excessive current.
＊Make sure the +/- wiring is correct.
＊Wiring should be made before inserting
into the driver card.

In case of using UL recognized product.
* Battery shall not be used for power supply.

① Supply 24VDC to the driver card, and the LED 1 (green)
illuminates.
② Close the contact of CN2-1 , and the MDR starts
running.

OFF* 0V should be common to the power voltage.
* 3mA current is drawn to CN2-1.
* Wait 1 second after the driver card is powered before
running MDR.

5-1 Speed Variation
Speed of the MDR can be varied either internally by integral dip switch or externally byanalog voltage input.
・Range of speed variation differs according to the MDR model. Check the nominal
speed of the model from the circular label put on its end housing.
ExamplePM486FE-60-400-D-024
Nominal Speed【5-1-1 Internal Speed variation 】①Set the SW1-2 OFF to effect the internal speed variation.
②With the combination of SW1-5 and Rotary Switch SW5, speed can be varied in 20
steps.

OFF【5-1-2 External Speed Variation 】① Set the SW1-2 ON to effect the external speed variation.
② Inject and vary the analog voltage between 0 and 10V to CN2-3 to vary the motor
speed in 20 steps.
＊ Max 2mA current is consumed at CN2-3.
＊ The analog voltage input should not exceed 10V. Its 0V should be common to
the Power voltage.

Caution●To monitor the error signal, a protective resistor should be mounted tosuppress 24VDC to 25mA or less.
●The driver card has 100Ω protective resistor.
Error signal is discharged from CN2-4・Disregard the error signal discharged when power is injected to the driver card(for 0.5 sec) and when power to the driver card is shut off (for 2 seconds)① SW1-4 allows the selection of the error signal discharge timing: discharge on normal status ordischarge when error arises. Error signal is NPN open collector in cace of CB-016N6/BN6.
＊See section 8 for error status, reset and history.

●100Ω resistor is built-in the driver card's output section for motor pulse
signal.
・MDR's motor pulse signal is discharged from CN2-5.

8-1 Error History
If thermister, motor stall or under voltage error arises while the MDR is running,
the error status and frequency of error occurrence are identified by LED 2 and LED 3.
・LED of error history will not illuminate during normal operational condition, butwhen motor stops with next error.
・Please see section 8-2 for other type of error.

LED indication

・To reset the error status, first remove the cause of error, and then switch thedirection signal at CN2-2.
・To restart the MDR, first remove the cause of error, and then re-inject
run signal at CN2-1.
・Please have 100ms or more intervals between each switch for ON→OFF→ON /OFF→ON→OFF / RUN→STOP→RUN to release error signal or restart MDR.
