Precautions for use
1 Introduction

4 Precautions for use
This chapter explains restrictions and requirements the user should consider when using the product.
zAlways use Oriental Motor cables to connect a motor and a driver.
Check on the Oriental Motor Website for the model of cables.
zWhen conducting the insulation resistance measurement or the dielectric strength test, be sure to
separate the connection between the motor and the driver.
Conducting the insulation resistance measurement or the dielectric strength test with the motor and driver
connected may result in damage to the product.
zPreventing leakage current
Stray capacitance exists between the driver’s current-carrying line and other current-carrying lines, the earth and the
motor, respectively. A high-frequency current may leak out through such capacitance, having a detrimental eect on
the surrounding equipment. The actual leakage current depends on the driver’s switching frequency, the length of
wiring between the driver and motor, and so on. When installing an earth leakage breaker, use a product oering
resistance against high frequency current such as the one specied below.
Mitsubishi Electric Corporation: NV series
zIf vertical drive (gravitational operation) such as elevating applications is performed or if sudden start-
stop operation of a large inertia is repeated frequently, connect the Oriental Motor’s regeneration
resistor RGB200.
The setting to use the built-in regeneration resistor is applied at the time of shipment. Using the built-in regeneration
resistor, however, continuous regeneration operation, vertical drive (gravitational operation) such as elevating
applications, or sudden start-stop operation of a large inertia cannot be performed. When performing such operation,
use the Oriental Motor’s regeneration resistor RGB200. Refer to the OPERATING MANUAL Hardware Edition for the
connection method.
zPrecaution when connecting a main power supply and a control power supply in a state of grounding
the positive side
The USB connector, CN5, CN6, and CN7 connectors on the driver are not electrically insulated. When grounding the
positive terminal of the power supply, do not connect any equipment (PC, etc.) whose negative terminal is grounded.
Doing so may cause the driver and this equipment to short, damaging both. When connecting, do not ground
equipment.
zSaving data to the non-volatile memory
Do not turn o the control power supply while writing the data to the non-volatile memory, and also do not turn o
for ve seconds after the completion of writing the data. Doing so may abort writing the data and cause an alarm of
EEPROM error to generate. The non-volatile memory can be rewritten approximately 100,000 times.
zNoise elimination measures
Refer to the OPERATING MANUAL Hardware Edition for noise elimination measures.

2 Before starting operation
17
2 Copy the ABZO information (xed value)
to the driver
For parameters of a motorized actuator, the dierent values have been stored in the ABZO sensor and the driver,
respectively.
The values based on the product specications such as the recommended macro operation or coordinate information
are stored in the ABZO sensor of a motorized actuator. The values stored in the ABZO sensor cannot be changed
because of the xed value.
Meantime, the values for the standard type (motor only) are stored in the driver parameters.
In a state of the factory shipment, the parameter information (xed value) stored in the ABZO sensor is used
preferentially. However, if a parameter is changed with the MEXE02 soft ware or others, all parameters including the
changed parameter will be changed to the values set in the driver. Therefore, an unexpected movement may cause
when operation is executed. In order to prevent such problems, copy the ABZO information (xed value) to the driver,
and match the data in the driver parameter with the xed value in the ABZO sensor.
Before copying the ABZO information (xed value) of the product to the driver,once the parameter
(such as electronic gear) is changed to "Manual setting" using the MEXE02 software and written to
the driver, the parameter having changed will not return to the xed value even if the ABZO
information (xed value) is copied.
Procedure
Using the MEXE02 software, copy the ABZO information (xed value) of the ABZO sensor to the driver.
1. Turn on the control power supply of the driver.
2. Click [Copy the ABZO (xed) information to the driver in a lump] under the [Communication] menu.
The ABZO information (xed value) is copied to the driver.
3. Turn on the control power supply of the driver again.
4. Check whether the copied data is updated on the unit information monitor window.
The contents of each item are shown in the table.

3 Setting of resolution
Set the resolution when using in combination with a mechanism, such as a geared motor or a motorized actuator.
If the "Electronic gear A" and "Electronic gear B" parameters are set, the resolution per revolution of the motor output
shaft can be set.
Note that the calculated value must fall within the setting range specied below.
Setting range of resolution: 100 to 10,000 P/R (Initial value: 1,000 P/R)
Resolution (P/R) = 1,000

Electronic gear A Sets the denominator of the electronic
gear. 1 to 65,535 1
Electronic gear B Sets the numerator of the electronic
gear.
•When the "Mechanism settings" parameter is changed, turn o the control power supply of the
driver and on again.
•If a resolution out of the setting range is set, information of Electronic gear setting error will be
generated. If the control power supply is turned on again or Conguration is executed in a state
where information of Electronic gear setting error is generated, an alarm of Electronic gear setting
error will be generated.
•If the resolution was changed after preset was executed in a state where the "Preset position"
parameter is set to other than "0," execute preset once again. If the "Preset position" parameter is
set to "0," the present position is automatically recalculated even if the resolution is changed.
The initial value of the resolution may vary depending on the product connected.
Calculation method of electronic gears A and B
This section explains how to calculate the electronic gears A and B with examples of a ball screw and rotary table.
zCalculation example 1: Ball screw
•When a ball screw with a lead of 12 mm should be moved 0.01 mm per step.
•Gear ratio: 1 (No speed reduction mechanism between the motor and ball screw.)
Resolution on mechanism = 1,000

By calculation:
Therefore, the electronic gear A is 10 and the electronic gear B is 12, and the resolution is 1,200 P/R.

Therefore, the electronic gear A is 10 and the electronic gear B is 36, and the resolution is 3,600 P/R.
Resolution for phase A (ASG) output and phase B (BSG) output
The phase A output and phase B output are pulse signals output from the ABZO sensor. Since pulses are output from
the phase A and phase B outputs in response to the motor operation, the motor position can be monitored by
counting the number of pulses.
The resolution for the phase A and phase B outputs is the same as the motor resolution when the control power
supply is turned on. If the motor resolution is changed, the resolution for the phase A and phase B outputs is also
changed.

4 Home setting
The home has not set at the time of shipment. Before starting operation, be sure to set the home.
Perform the home setting only once initially. Once the home is xed, the home information is retained even if the
power supply is shut o.
The home is written to the non-volatile memory. The non-volatile memory can be rewritten
approximately 100,000 times.
Home setting method
Use the HOME PRESET switch to set the home.
PWR/ALM LED
HOME PRESET
switch
1. Move the output shaft to the position that is desired to set as the home.
2. Check the control power supply has been turned on, and press and hold the HOME PRESET switch for one second.
The PWR/ALM LED blinks in red and green at the same time. (Red and green colors may overlap and it may be
visible to orange.)
3. Release a hand o within three seconds after the PWR/ALM LED started blinking, and press the HOME PRESET
switch again within three seconds after releasing the hand o.
The PWR/ALM LED is lit in red and green at the same time, and then it is lit in green only.
4. The home is set.
For the operation of the step 3, be sure to release a hand o after the PWR/ALM LED started blinking
and perform within three seconds. If three seconds elapsed in either of the two processes, the PWR/
ALM LED is returned to the state of being lit in green. In this case, perform from the procedure 2
again.
