4) Motor temperature chart

Minimized heat generation by managing the current flowing

through the motor with load.

5) Tuning not required

Tuning is unnecessary even with load changes. (no gain tun-

ing)

Proper usage

Troubleshooting

1. When motor does not rotate

①Check the connection status between controller and driver, and

pulse input specifications (voltage, width).

②Check the pulse and direction signal is connected correctly.

2. When motor rotates to the opposite direction of the

designated direction

①When RUN mode is 1-pulse method, CCW input [H] is for

forward, [L] is for backward.

②When RUN mode is 2-pulse method, check CW and CCW

pulse input is changed.

3. When motor drive is unstable

①Check that driver and motor is connected correctly.

②Check the driver pulse input specifications (voltage, width).

Caution during use

Motor

1. Do not disassemble or modify the product.

It may cause malfunction due to small dregs. Once disassembling

the motor, its performance would significantly decline.

2. Do not impact the motor.

The air-gap, the distance between rotator and stator is processed

as 0.05mm, but if it is impacted, the balance of air-gap can be

broken and it may cause a malfunction.

This encoder consists of precision components. Therefore, if

it is dropped or has strong shock, it may lose the function or

generates wrong output pulses.

3. Using at low temperature

Using motors at low temperature may cause reducing maximum

starting / driving characteristics of the motor as ball bearing's

grease consistency decreases due to low temperature. (Note

that the lower the bearing's grease consistency, the higher the

bearing's friction torques.) Start the motor in a steady manner

since motor's torque is not to be influenced.

4. Temperature rise

The surface temperature of motor shall be under 100℃ and it

can be significantly increased by operation conditions. In this

case, use the cooling fan to lower the temperature forcedly.

5. Insulation resistance measurement, Dielectric strength test

When executing insulation resistance measurement or dielectric

strength test when motor and driver are connected, it may cause

damage to the unit.

6. Maintenance, Inspection

For using motor, it is recommended to Maintenance and

inspection regularly.

If motor has error, do not use the motor. Take maintenance and

inspection before using it.

Maintenance and inspection items are as below.

①Unwinding bolt and connection parts for the unit installation

and load connection

②Strange sound from ball bearing of the unit

③Damage and Stress of lead cable of the unit

④Connection error with driver

⑤Inconsistency between the axis of motor output and the center,

concentric (eccentric, declination) of the load, etc.

Driver

1. Caution for signal input

If the signal input supply is higher than rated supply in the

specification, connect the additional resistance to external part.

(Connect 3kΩ of resistance when applying 24V of power)

2. Caution for wiring

( ※ Autonics product is recommended)

① Use twisted pair (over 0.2mm

should be shorter than 2m.

② The thickness of cable should be same or thicker than the

motor cable's when extending the motor cable.

③ Must separate between the signal cable and the power cable

over 10cm.

3. Caution for installation

For heat radiation when installing this unit, contact this driver

base tightly with the metal surface. When using this unit,

overheat error occur, install a fan for heat radiation or change the

installation placement.

4. Caution for re-supplying power

Re-supply power after min. 1 sec. from disconnected power.

5. Motor vibration and noise can occur in specific frequency

period

①Motor vibration and noise can be lowered by change motor

installation or attach damper.

②Use the unit in a range without vibration and noise range by

RUN speed adjustment.

6. This product may be used in the following environments

①It shall be used indoor

②Altitude up to 2,000m

③Pollution degree 2
