1. Usage

WARNING

The MELIPM series motor is a synchronous motor with high-performance

magnets built in its rotor. Therefore, after the drive unit is powered off, there are high voltages at the motor ter mi nals while the motor is running. Before starting wiring or maintenance and inspection, make sure that the motor has stopped. In any application wh er e the motor is rotated by a load su ch as a fan or blower, connect a low -voltage manual switch on the drive unit' s output side, open the switch, and start w iring or maintenance and inspe ction. Not doing so can cause an electric shock.

Never disassem ble or modify the unit. Doing so can cause an electric shock,

fire or injury.

Do not use the unit with any load other than th e specified motor. Doing so

can cause a fire or injury.

Provide safety devices for the whole system, e.g. emergency brakes, to

ensure that the machine or device is not placed in hazardous c onditions

when the drive unit fails.

CAUTION

If a holding brake is required, prepare it separately. Injury may result. Before operating the drive unit which had been stored for an extended

period of time, perform inspection and test operation on the unit before

using. Not doing so may cau s e accidents.

Page 5

4. Wiring

WARNING

Any person who is involv ed in the wiring of this equipment should b e fully

competent to do the work. Otherwise, an electric shock or fire can occur.

Install a no-fuse breaker or earth leakage circuit breake r. Othe rwise, a drive

unit failure can cause large currents to flow, resulting in a fire.

Always install the unit before wiring. Otherw is e, an electric shock or fire can

occur.

Before restarting wiring after pow er-on, make sure that the motor is at a stop,

wait for more than 10 minutes after switching power off, and confirm that the DC voltage across the DC terminals P/+ and N/- is low enou gh to do the work. Immediately after power-off, the DC terminals P/+, N/- are charged with more than 200V (residual voltage of th e inter nal capacitor). Therefore, an electric shock may occur.

Even after power-off, the motor connection terminals U, V, W have high

voltages while the motor is running. Alw ays start wiring after confirming that the motor has stopped. Not doing so can cause an electric shock.

Earth the drive unit. Not doing so can cause an electric shock o r fire.

CAUTION

Make sure that the input power supply voltage matches the rated voltage

specifications. Mismatc h c an cause a fire or accidents.

Check the terminal layout and ter minal symbols to ensure that connection s

are correct. Wrong connection s can cause a fire or accidents.

Do not connect a power supply to the motor connection ter minals U, V, W.

Doing so can caus e a fire or accidents.

Connect the motor connection terminals U, V, W to match the motor phase

sequence. Wrong connections can cause a ccidents due to reverse rotation of the motor.

Do not connect a resistor across the DC terminals P/+-N/-. Doing so can

cause a fire or accidents.

Take measures to prevent peripheral sensors and equipment from

malfunctioning due to electromagnetic noises. Not doing so can cause accidents.

Take measures to prevent peripheral power capacitors and generators from

overheating or being damaged due to power harmonics. Not d oing so can cause a fire.

Connect the power capacitor, surge suppressor an d r adio noise filter (FR-

BIF option) on the power supply side. Connection on the output side can cause a fire.

Page 6

5. Operation WARNING

Always replace the front cover befo re switching input power on. While power

is on, do not remove the front cover. D oing so can cause an electric shock.

Operate the switches with dry hands. Not doing so can cause an electric

shock.

Prepare an emergency stop switch separately. The "STOP/RESET" key of

the parameter unit is valid for stop ping only when the function setting has been made. Not using a se parate emergency stop switch can cause accidents. When the stall prevention function is activated, operation will be performed

independently of the preset acceleration/deceleration time and preset speed. Design the machine to ensu re safety if the stall prevention function is activated. Not doing so can c ause accidents.

At the occurrence of an alarm, turn off the run signal before resetting the

alarm. The drive unit will restart abruptly if you reset the alarm with the run signal on. It can cause injury.

At occurrence of an alarm, turn off the run sig nal. If you do not turn off the

run signal, the alarm may be reset due to power OFF-ON at occur rence of an instantaneous pow er failure or like, restarting the drive unit suddenly. It can cause injury.

CAUTION

You can set the motor speed easily between low speed and high speed. Set

the speed command which will not exceed the permissible range of machine design. Not doing so can cause accidents.

If the motor is rotated by the load, ensure that the motor will not exceed its

maximum speed. The drive unit may be damaged.

While power is on or some time after power-off, do not touch the heat sink

and brake resistor as they are hot. You may get burnt.

The electronic overcurrent protection function for motor overheat protection

is initialized when the drive unit is reset. Frequent resetting of the drive unit will disable motor overheat protection. The motor may be burnt if it is operated under overload.

6. Maintenance, Inspection and Part (Cooling Fan) Replacement

WARNING

Any person who is involved in maintenance, inspection or part replacement

should be fully competent to do the work. Otherwise, an electric shock or injury can occur.

Before starting maintenance, inspection or part replacement, make sure that

the motor is at a stop, wait for more than 10 minutes after switching power off, and confirm that the DC voltage across the DC terminals P/+ and N/- is low enough to do the work. Immediately after power-off, the DC terminals P/+, N/- are charged with more than 200V (residual voltage of the internal capacitor). Therefore, an electric shock may oc cur.

Even after power-off, the motor connection terminals U, V, W have high

voltages while the motor is running. Always start the work after confirming that the motor has stopped. Not doing so can cause an electric shock.

Do not conduct a pressure test. A pressure test can damage the drive unit.

Do not perform an insulation resistance test on the control circuit using a

megger. Such a test can damage the d rive unit.

While power is on, do not replace the cooling fan. Replacing the cooling fan

during power-on c an be hazardous.

Any person who is involved in the wiring of this equipment should be

fully competent to do the work. Otherwise, an electric shock or fire can occur.

Always install the unit before wirin g. Otherwise, an electric shock or

fire can occur.

Before restarting wiring after switching power "ON", make sure that the

motor is at a stop, wait for more than 10 minutes after switching power "OFF", and confirm that the DC voltage across the DC terminals P/+ and N/- is low enough to do wiring. Immediately after power "OFF", the DC terminals P/+, N/- are charged with more than 200V (residual voltage of the internal capacitor). Therefore, an electric shock may occur.

Even after power-off, the motor connection terminals U, V, W hav e high

voltages while the motor is running. Always start wiring after confirming that the mo tor has stopped. Not doing so can cause an electric shock.

CAUTION

Take measures to prevent peripheral sensors and equipm ent from

malfunctioning due to electromagne tic noises. Not doing so can cause accidents.

Take measures to prevent peripheral power capacitors and generators

from overheating or being damaged du e to power harmonics. Not doing so can cause a fire.

Do not leave wire offcuts in the drive unit. Doing so can cause a fault,

failure or malfunction.

If the machine must not be restarted when power is restored after a

power failure, provide a magnetic contactor on the power supply side and also make up a sequence which will not turn "ON" the start signal automatically when power is restored.

Tighten the terminal screws to the specified torque. Undertightening

can cause an inter-terminal short circuit or malfunction. Overtightening can cause the screws and unit to be damaged, resulting in a short circuit, malfunction or the like.

Time

The minimum value of acceleration/deceleration time is 0.5s. Any

acceleration/deceleration time setting of less than 0.5 is handled a s

0.5s.

The upper limit of acceleration time at up to 500r/min is 20s

(conversion value up to rated speed). When the acceleration time setting is greater than 20s, therefor e, the acceleration time required to reach the acceleration/decele ration reference speed is represented by the following expression and is shorter than the preset acceleration time:

Required acceleration time = 1.4 + T1 T1 = (preset speed co mmand - 500) × Pr. 7 setting

/Pr. 20 setting During deceleration, the motor will coast at less than 300r/min. Therefore, the time required for de c eleration from the speed set in Pr. 20 to 300r/min is as follows:

Required deceleration time = Pr. 8 setting × (Pr. 20 setting - 300)

/ Pr. 20 setting

A too short acceleration/deceleration time setting can cause an

abnormal stop due to overload, overcurrent or overvoltage. Make a setting which will not display overload on the parameter unit.

Setting Range Unit Remarks

0, 60.0 to 200.0 % When 0 is set, the stall prevention function is not activated.

When the output current reaches the Pr. 22 setting, the speed is varied with the running status to suppr ess the torque. The setting is based on the rated motor current. When the stall prevention function is activated, OL appears on the screen of the FR-PU04 parameter unit. That the stall prevention function has been activated can be exported as OL si gnal fr om the terminal.

Refer to: 8.7.2 Selection of the control circuit

MEMO

If the stall prevention function is activated during acceleration or

deceleration, the acceleration or de c eleration time [Section 8.5.2] will be longer than the setting. When the travel of a ma chine or the like is determined by the acceleration or deceleration time, the travel will increase due to the operation of the stall prevention function.

If the stall prevention function is activated during constant speed

operation, the running speed may vary abruptly.

8 PARAMETER FUNCTIONS

Once the motor speed ha s reached or exceeded the speed set in the corresponding parameter, it is exported from the control circuit output terminals where the FU signal ha s been assigned.

Pr. 43 is valid for only the operation performed using the reverse r otation signal (terminal STR or REV

key). Setting the Pr. 43 value makes the Pr. 42 setting invalid for reverse rotation signal operation so that you can separate detection between forwa rd rotation operation and reverse rotation operation. Setting "9999" in Pr. 43 provides the same function as set in Pr. 42.

If the motor current remains higher than the Pr. 150 setting for longer than the time set in Pr. 151, the terminal where the assigned Y12 signal turns "ON". Th e Pr. 150 value is based on the rated motor current. Use any of Pr. 190, Pr. 194 [Section 8.7.2] to assign the ter minal u se d for Y1 2 signal output. Once turned on, the Y12 sign al r emains on for at least 100ms.
