CAUTION

3. Various precautions

Observe the following precautions. Incorrect handling of the unit could lead to faults, injuries and electric shocks, etc.

(1) Transportation and installation

Correctly transport the product according to its weight. Use the servomotor's hanging bolts only when transporting the servomotor. Do not transport

the servomotor when it is installed on the machine. Do not stack the products above the tolerable number. Do not hold the cables, axis or detector when transporting the servomotor. Do not hold the connected wires or cables when transporting the servo drive units. Do not hold the front cover when transporting the servo drive units. The unit could drop. Follow this Instruction Manual and install in a place where the weight can be borne. Do not get on top of or place heavy objects on the unit. Always observe the installation directions. Secure the specified distance between the servo drive unit and control panel's inne r wall, and

between other devices. Do not install or run a servo drive unit or servomotor that is damaged or missing parts. Do not block the intake or exhaust ports of the servomotor provided with a cooling fan. Do not let foreign objects enter the servo drive units or servomotors. In particular, if

conductive objects such as screws or metal chips, etc., or combustible materials such as oil enter, rupture or breakage could occur.

The servo drive units and servomotors are precision devices, so do not drop them or apply strong impacts to them.

CAUTION

Store and use the units under the following environment conditions.

Ambient temperature 0°C to +55°C (with no freezing) 0°C to +40°C (with no freezing) Ambient humidity Storage temperature -15°C to +70°C

Storage humidity 90%RH or less (with no dew condensation)

Atmosphere

Altitude 1,000m or less above sea level

Environment

Vibration 4.9m/s

Securely fix the servomotor to the machine. Insufficient fixing could lead to the servomotor slipping off during operation.

Always install the servomotor with reduction gear in the designated direction. Failure to do so could lead to oil leaks.

Structure the rotary sections of the motor so that it can never be touched during operation. Install a cover, etc., on the shaft.

When installing a coupling to a servomotor shaft end, do not apply an impact by hammering, etc. The detector could be damaged.

Do not apply a load exceeding the tolerable load onto the servomotor shaft. The shaft could break.

Store the motor in the package box. When inserting the shaft into the built-in IPM motor, do not heat the rotor higher than

130°C. The magnet could be demagnetized, and the specifications characteristics will not be ensured.

If the unit has been stored for a long time, always check the operation before starting actual operation. Please contac t the Service Center or Service Station.

(2) Wiring

CAUTION

Correctly and securely perform the wiring. Failure to do so could lead to runaway of the servomotor.

Do not install a condensing capacitor, surge absorber or radio noise filter on the output side of the servo drive unit.

Correctly connect the output side (terminals U, V, W). Failure to do so could lead to abnormal operation of the servomotor.

Do not directly connect a commercial power supply to the servomotor. Failure to observe this could result in a fault.

When using an inductive load such as a relay, always connect a diode as a noise measure parallel to the load.

Controloutput signal

Control output signal

When using a capacitance load such as a lamp, always connect a protective resistor a s a noise measure serial to the load.

Do not reverse the direction of a diode which connect to a DC relay for the control output signals to suppress a surge. Connecting it backwards could cause the drive unit to malfunction so that signals are not output, and emergency stop and other safety circuits are inoperable.

Do not connect/disconnect the cables connected between the units while the power is ON. Securely tighten the cable connector fixing screw or fixing mechanism. An insecure fixing could

cause the cable to fall off while the power is ON. When using a shielded cable instructed in the connection manual, always ground the cable with

a cable clamp, etc. Always separate the signals wires from the drive wire and power line. Use wires and cables that have a wire diameter, heat resistance and flexibility that conforms to

the system.

(3) Trial operation and adjustment

Check and adjust each program and parameter before starting operation. Failure to do so could lead to unforeseen operation of the machine.

Do not make remarkable adjustments and changes as the operatio n could become unstable.

(4) Usage methods

Install an external emergency stop circuit so that the operation can be stopped and power shut off immediately.

Turn the power OFF immediately if smoke, abnormal noise or odors are generated from the servo drive unit or servomotor.

Unqualified persons must not disassemble or repair the unit. Never make modifications. Reduce magnetic damage by installing a noise filter. The electronic devices used near the

servo drive unit could be affected by magnetic noise. Use the servo drive unit, servomotor and regenerative resistor with the designated combination.

Failure to do so could lead to fires or trouble. The brake (magnetic brake) assembled into the servomotor is for holding, and must not be used

for normal braking. There may be cases when holding is not possible due to the magnetic brake's life or the

machine construction (when ball screw and servomotor are coupled via a timing belt, etc.). Install a stop device to ensure safety on the machine side.

After changing the programs/parameters or after maintenance and inspection, always test the operation before starting actual operation.

Do not enter the movable range of the machine during automatic operation. Never place body parts near or touch the spindle during rotation.

Follow the power supply specification conditions given in the separate specifications manual for the power (input voltage, input frequency, tolerable sudden power failure time, etc.).

Set all bits to "0" if they are indicated as not used or empty in the explanation on the bits. Do not use the dynamic brakes except during the emergency stop. Continued use of the

dynamic brakes could result in brake damage. If a breaker is shared by several power supply units, the breaker may not activate when a

short-circuit fault occurs in a small capacity unit. This is dangerous, so never share the breakers.

CAUTION

(5) Troubleshooting

If a hazardous situation is predicted during power failure or product trouble, use a servomotor with magnetic brakes or install an external brake mechanism.

Use a double circuit configuration that allows the operation circuit for the magnetic brakes to be operated even by the external emergency stop signal.

CAUTION

Shut off with the servomotor brake control output.

Always turn the input power OFF when an alarm occurs. Never go near the machine after restoring the power after a power failure, as the machine

could start suddenly. (Design the machine so that personal safety can be ensured even if the machine starts suddenly.)

(6) Maintenance, inspection and part replacement

Always carry out maintenance and inspection after backing up the servo drive unit's programs or parameters.

The capacity of the electrolytic capacitor will drop over time. To prevent secondary disasters due to failures, replacing this part every five years when used under a normal environment is recommended. Contact the Service Center or Service Station for replacement.

Do not perform a megger test (insulation resistance measurement) during inspections. If the battery low warning is issued, save the machining programs, tool data and parameters

with an input/output unit, and then replace the battery. Do not short circuit, charge, overheat, incinerate or disassemble the battery.

(7) Disposal

Treat this unit as general industrial waste. Note that MDS Series unit with a heat dissipating fin protruding from the back of the unit contains substitute Freon. Do not dispose of this type of unit as general industrial waste. Always return to the Service Center or Service Station.

Do not disassemble the servo drive unit or servomotor parts. Dispose of the battery according to local laws.

(8) General precautions The drawings given in this Specifications and Maintenance Instruction Manual show the covers and

safety partitions, etc., removed to provide a clearer explanation. Always return the covers or partitions to their respective places before starting operation, and always follow the instructions given in this manual.

1-2-3 Prevention of entering of foreign matter

Treat the cabinet with the following items.

• Make sure that the cable inlet is dust and oil proof by using packing, etc.

• Make sure that the external air does not enter inside by using head radiating holes, etc.

• Close all clearances.

• Securely install door packing.

• If there is a rear cover, always apply packing.

• Oil will tend to accumulate on the top. Take special

measures such as oil-proofing to the top so that oil does not enter the cabinet from the screw holds.

• After installing each unit, avoid machining in the periphery. If cutting chips, etc., stick onto the electronic parts, trouble may occur.

• When using the unit in an area with toxic gases or high levels of dust, protect the unit with air purging (system to blow clean air so that the panel's inner pressure is higher than the outer pressure).

(4) Cautions

[1] Do not apply impacts on the magnet. Do not install strong magnets near the magnet. [2] Sufficiently clean the surrounding area so that iron chips and cutting chips do not adhere to the

magnet. Demagnetize the round disk before installing.

[3] Securely install the magnet onto the spindle with an M4 screw. Take measures to prevent

screw loosening as required. [4] Balance the entire spindle rotation with the magnet installed. [5] Install a magnet that matches the spindle's rotation speed. [6] When installing the magnet onto a rotating body's plane, set the speed to 6,000r/min or less. [7] Install so that the center line at the end of the head matches the center of the magnet. [8] The BKO-C1730 is not an oil-proof product. Make sure that oil does not come in contact with

BNO-C1730 or BKO-C1810. [9] When connecting to the spindle drive unit, wire so that the effect of noise is suppressed.

1-4 Noise measures

Noise includes "propagation noise" generated from the power supply or relay, etc., and propagated along a cable causing the power supply unit or drive unit to malfunction, and "radiated noise" propagated through air from a peripheral device, etc., and causing the power supply unit or drive unit to malfunction. Always implement these noise measures to prevent the peripheral devices and unit from malfunctioning. The measures differ according to the noise propagation path, so refer to the following explanation and take appropriate measures.

(1) General noise measures

• Avoid laying the drive unit's power line and signal wire in a parallel or bundled state. Always

separate these wires. Use a twisted pair shielded wire for the detector cable and signal wires such as the communication cable connected with the NC, and accurately ground the devices.

• Use one-point grounding for the drive unit and motor.

• Accurately ground the AC reactor.

(2) Propagation noise measures

Take the following measures when noise generating devices are installed and the power supply unit or drive unit could malfunction.

• Install a surge killer on devices (magnetic contacts, relays, etc.) which generate high levels of

noise.

• Install a power line filter in the stage before the power supply unit.

• Install a ferrite core on the signal wire.

• Ground the shield of the servo detector's cable with a cable clamp.

• Wire the spindle PLG detector cable away from other wires.

(3) Measures against radiated noise

The types of propagation paths of the noise and the noise measures for each propagation path are shown below.

Noise propagation path Measures

When devices such as instrument, receiver or sensor, which handle minute signals and are easily affected by noise, or the signal wire of these devices, are stored in the same panel as the drive units and the wiring is close, the device could malfunction due to airborne propagation of the noise. In this case, take the following measures.

[1] [2] [3]

[4] [5] [6]

[7]

[8]

(a) Install devices easily affected as far away from the drive units as possible. (b) Lay devices easily affected as far away from the signal wire of the drive unit as possible. (c) Avoid laying the signal wire and power line in a parallel or bundled state. (d) Insert a line noise filter on the input/output wire or a radio filter on the input to suppress the

noise radiated from the wires.

(e) Use a shield wire for the signal wire and power line, or place in separate metal ducts. If the signal wire is laid in parallel to the power line, or if it is bundled with the power line, the noise could be propagated to the signal wire and cause malfunction because of the magnetic induction noise or static induction noise. In this case, take the following measures.

(a) Install devices easily affected as far away from the drive unit as possible.

(b) Lay devices easily affected as far away from the signal wire of the drive unit as possible.

(d) Use a shield wire for the signal wire and power line, or place in separate metal ducts. If the power supply for the peripheral devices is connected to the power supply in the same system as the drive units, the noise generated from the power supply unit could back flow over the power line and cause the devices to malfunction. In this case, take the following measures.

(a) Install a radio filter on the power supply unit's power line.

(b) Install a power filter on the power supply unit's power line. If a closed loop is created by the peripheral device and drive unit's grounding wire, a leakage current could flow and cause the device to malfunction. In this case, change the device grounding methods and the grounding place.

2-5 Connection of power supply

1. Make sure that the power supply voltage is within the specified range of each unit. Failure to observe this could lead to damage or faults.

2. For safety purposes, always install a No-fuse breaker (NFB), and make sure that the circuit is cut off when an error occurs or during inspections.

3. The wire size will differ according to each drive unit capacity.

CAUTION

2-5-1 Power supply input connection

(1) When using one power supply unit

Install the drive units so that the distance between power supply unit and spindle drive unit will be 3cm or less.

4. For safety purposes, always install a magnetic contactor (contactor) on the main circuit power supply input. Large rush currents will flow when the power is turned ON.

5. A semiconductor element is used in the power supply unit's magnetic contact drive circuit, and a surge absorber is installed to protect the element. Therefore, a leakage current of approx. 15mA is passed. Confirm that the exciting coil in the magnetic contact will not function at 15mA or less.

2-6-3 Spindle coil changeover

There are spindle motors capable of coil changeover control, which enables favorable characteristics to be attained from low speeds to high speeds by changing two types of coils.

(1) Coil changeover control

The speed at which to change the coils is detected by the spindle drive according to the value set with spindle parameter SP020. This is conveyed to the NC or PC with a speed detection (SD) signal. The NC or PC judges the other conditions (coil fixed, etc.), and issue a coil changeover command to the spindle drive with the L coil selection command (LCS). To prevent the contactor from varying, the hysteresis set with SP047 is applied on the speed when changing from the low-speed coil to the high-speed coil and the high-speed coil to the low-speed coil.

(2) Protective functions

[1] Base shutoff after a winding changeover

When the L-coil selection command (LCS) is used to perform low-speed winding → high-speed winding switching, or vice-versa, this base is shut off during contactor operation time in order to protect the spindle drive unit's main circuit. This base shutoff time is determined by the "Winding changeover base shutoff timer" (SP059) setting. The standard time setting should be used, as a shorter time can cause contactor burn damage.

[2] Current limit after coil changeover

Following a coil changeover, the current is limited (SP061) for the period specified by the current limit timer (SP060) in order to stabilize control. When the synchronous tap control is executed immediately after the coil changeover, the output current is limited to the value set in SP061, therefore apply the sequence to execute the position control after the current limit is cancelled.

Besides the emergency stop input from the NC or PC to spindle drive unit, double-protection when an emergency stop occurs can be provided by directly inputting an external emergency stop to the CN23 connector on the power supply unit. Even if the emergency stop is not input from CNC for some reason, the contactors will be shut off by the external emergency stop input from CN23 connector on the power supply unit.

[2] Setting

When using the external emergency stop, the rotary switch on the front of the power supply unit and the parameter (PTYP) of drive unit that controls the power supply must be set.

• Rotary switch setting: 4

• Parameter setting: Add "0040" to the setting of PTYP (SP041).

(2) Operation sequences of CN23 external emergency stop function

If only external emergency stop is input when external emergency stop valid is set in the parameters (the emergency stop is not input in the spindle drive unit), an "In external emergency stop" (warning EA) will be detected. At this time, the spindle drive unit does not enter an emergency stop status. (There will be no deceleration control.) If an emergency stop is not issued for the spindle drive unit within 30 seconds and the setting time of SP055 after the external emergency stop is input, the power supply unit outputs contactor shutoff signal (MC1), and then it shuts off the contactors, and a power supply error (alarm 6F) is detected simultaneously. If the emergency stop is input within 30 seconds and the setting time of SP055, the warning EA replaces the "In emergency stop" (warning E7). A normal emergency stop status will result if the contactor shutoff command is further input. When the setting value of SP192 is set to "2" or "3", a power supply error (alarm 6F) will occur even if the emergency stop is input within 30 seconds and the setting time of SP055. Ready ON is possible even if CN23, an external emergency stop has been input when the emergency stop is canceled, but a power supply error (alarm 6F) will occur after 30 seconds.

(3) Example of emergency stop circuit

[1] Outline of function

The power supply unit's external emergency stop can be validated by wiring to the CN23 connector, and setting the parameters and rotary switch. If the emergency stop cannot be processed and the external contractor cannot be shut off (due to a fault) by the spindle drive unit, the external contactor can be shut off by the power supply unit instead of the spindle drive unit. At this time, the spindle motor will coast to stop. EN60204-1 Category 1 can be basically complied with by inputting the external emergency stop and installing contactor.

1. The power supply unit external emergency stop function is a function that assists the NC emergency stop.

CAUTION

2. It will take 30 seconds for the external contactor to function after the emergency stop is input to CN23. (This time is fixed.)

[2] Outline of function

The emergency stop is a signal used to stop the machine in an emergency. This is connected to the NC unit. Wire to the power supply unit when necessary. The servo/spindle unit will be decelerated and controlled by the software according to the emergency stop command issued from the NC unit. (The deceleration control depends on a parameter setting.) The diagram on the right shows an example of the emergency stop circuit (EN60204-1 Category 0 stop) in which an off delay timer (TM1) is installed as a power shutoff method independent from the NC emergency stop input. The required safety category may be high depending on the machine and the Safety Standards may not be met. Thus, always pay special attention when selecting the parts and designing the circuit.

[3] Setting the off delay timer (TM1) time

Set the TM1 operation time so that it functions after it has been confirmed that all axes have stopped. If the set time is too short, the spindle motor will coast to a stop.

Provide a mechanism that shuts off the power even if the NC system fails.

3-2 Setting the initial parameters for the spindle drive unit

The parameters of spindle drive unit must be set before the spindle system can be started up. Basic settings have been provided in shipping. Therefore, for parameters required to be changed individually, they are input with the rotary switch and push button of the drive unit or the personal computer.

3-2-1 Parameter setting method

There are two methods of parameter setting as shown below.

(a) Setting by the personal computer (b) Setting by the spindle drive unit 7-segment, rotary switch and push-buttons

The method (b) is explained in this section.

(1) Layout of display unit

Open the cover on the right side of the LED located in the upper part of the spindle drive unit. The following switch and push-buttons are found there.

3. When the parameter is changed with this method, always turn the spindle

1) Turn the drive unit main power supply ON.

2) Set the rotary SW to "1". At this time, main/sub is displayed on the left side of the spindle drive unit 7-segment LED, and the upper one digit of the parameter No. is displayed on the other side.

[1] Set the upper digit of parameter No. with UP/DOWN buttons.

Set "0" for the parameter No. SP255 or lower, set "1" for the parameter No. SP256 or higher.

[2] Switch Main/Sub with SET button. Main and Sub switch every time the SET button is pressed.

When "1" is displayed on the left side of LED, "Main" is selected; when "2" is displayed, "Sub" is selected. Set at the main side for all the specifications other than 1A2M.

3-2-2 List of spindle parameters

These parameters are sent to the spindle drive unit when the NC power is turned ON. The standard parameters are designated with the "Spindle parameter setting list" enclosed when the spindle motor is delivered. There may be cases when the machine specifications are unclear, so the parameters determined by the machine specifications should be confirmed by the user.

The orientation time will be shorter when the value is increased, and the servo rigidity will increase. On the other hand, the vibration will increase, and the machine will sway easily.

Set the position error range in which an orientation completion signal is output.

Set the motor speed limit value to be used when the speed loop is changed to the position loop in orientation mode. When this parameter is set to "0", SP017 (TSP) becomes the limit value. In the spindle side speed clamp valid (SP097:SPEC0-bit4＝1), the speed limit value will be the spindle speed instead of the motor speed.

As the set value is larger, the orientation time becomes shorter. However, the machine becomes likely to overshoot.

Set the stop position for orientation. (1) Motor PLG and spindle side detector Set a value obtained by dividing 360° by 4096. (2) Magnetic sensor orientation Divide -5°C to +5° by 1024, and set 0° as "0".

3. Setup

3-3 Initial adjustment of the spindle PLG

3-3-1 Adjusting the PLG installation

The PLG (spindle motor speed detector) mounted on the Mitsubishi framed spindle motor is shipped from Mitsubishi in the adjusted state. If there are no particular problems, carrying out the adjustment in this section is not required. When dismantling a motor, or when using the built-in spindle, the PLG detector is installed by the user, so the PLG sensor's gap and output signal must be adjusted with the following procedures. After installing and adjusting these, carry out automatic adjustment of the PLG according to each system. Install the PLG and then adjust following the procedures on the right. The output signal waveform can be retrieved from the check terminal on the PCB. Measure the waveform with an oscilloscope. The A/B phase output signal and the Z phase pulse width can be adjusted with the volume (VR1 to VR5) on the PCB. (The pulse width has been adjusted at shipment, and normally does not need to be adjusted.)

(1) Checking the gap

Check that the gap between the sensor detection surface and detection gear circumference is within 0.15±0.01mm as shown below. The gap is adjusted before shipment, but an error could occur due to the effect of the dimensional difference of the notched fitting section provided for installation, or the dimensional difference of the detection gears' outer diameter. If deviated from the above range, adjust the gap following the section "(2) Adjusting the gap".

(2) Adjusting the gap

[1] Confirm that the detection gears are not rotating. The sensor could be damaged if the gap is

adjusted while the gears are rotating. [2] Loosen the sensor fixing screw with the sensor fixed on the sensor installation seat. [3] Using a clearance gauge, adjust so that the gap between the sensor detection surface and the

detection gears' circumference is 0.15±0.01mm. [4] The sensor can be moved up and down or turned when the sensor fixing screw is loosened.

Position the rotating direction to match the marking line drawn on the sensor and installation

seat. [5] When done adjusting the gap, apply a locking agent on the sensor fixing screw, and then fix

the sensor. [6] After fixing the sensor, check the gap again. If operation is carried out with an excessively

small gap, the sensor and gears could contact, and the sensor could be damaged. [7] Faults could occur if an excessive external force is applied or if the sensor detection surface is

damaged.

(3) Checking the A phase and B phase output signal

Check the output signal waveform by measuring the signals of the check terminals on the PCB with the DC range of the synchroscope.

A phase output signal...... Across A-G

B phase output signal...... Across B-G

The PLG reference speed when confirming the output signal waveform differs according to the number of output pulses. Refer to the following table for the reference speed for each number of pulses. If operation is not possible at the reference speed, operate at a low speed within the range in which the waveform can be confirmed.

(4) Adjusting the A phase and B phase output signal

[1] Set the drive unit in the open loop operation state. (Set the spindle parameter SP038/bitF to

"1" and turn the spindle drive unit power ON again.) There are cases when sudden speed

changes cannot be followed during open loop operation, so gradually change the speed

command. [2] Forward run the motor and rotate the PLG at the reference speed. [3] Using the PCB volume VR1 to VR4, adjust so that the A phase and B phase signals are within

the specified range. If the correct waveform cannot be attained even after adjusting with VR1

to VR4, adjust the gap again. [4] Reverse run the motor and rotate the PLG at the reference speed. [5] Adjust the output waveform by adjusting VR1 to VR4 in the same manner.

voltage peak value is larger than 0.8V on both the plus side and minus side during both

forward run and reverse run. [8] Run the motor at the reference speed, and confirm that the A phase and B phase output signal

envelope is 0.4V or less.

The envelope is calculated by the expression below.

(5) Confirming the Z phase pulse width

Check the output signal waveform by measuring the signals of the check terminals on the PCB with the DC range of the synchroscope.

A phase output signal...... Across A-G

Z phase output signal...... Across Z-G

The output signal waveform is confirmed during motor forward run and reverse run. Set the synchroscope as follows to measure the waveform during each run direction.

During forward run .......... Apply a trigger at the rising edge of the Z phase output signal

During reverse run .......... Apply a trigger at the falling edge of the Z phase output signal

Confirm that the Z phase pulse width (time that the Z phase signal is at the "H" level = approx. 15V) is 40% or more and 60% or less, when one cycle of the A phase signal is calculated as 100%. The normal Z phase output signal waveform when run at the reference speed is shown below. If the output signal waveform is not as shown below, refer to the next section "(6) Adjusting the Z phase pulse width" and adjust. The Z phase pulse width has been adjusted at shipment, with a combination of the sensor section and PCB section having the same serial No. Thus, it normally does not need to be adjusted. If a sensor section and PCB section having different serial numbers must be used, causing the Z phase pulse width to deviate from the specified range, carry out the adjustment.

A phase output signal...... Across A-G

Z phase output signal...... Across Z-G

The output signal waveform is confirmed during motor forward run and reverse run. Set the synchroscope as follows to measure the waveform during each run direction.

During forward run ..... Apply a trigger at the rising edge of the Z phase output signal

During reverse run ..... Apply a trigger at the falling edge of the Z phase output signal

The phase difference for the Z phase signal and A phase signal is defined as follows.

During forward run ..... Time difference between Z phase output signal rising edge and A

phase output signal zero point (Q point)

During reverse run ..... Time difference between Z phase output signal falling edge and A

phase output signal's 1/2 cycle point (R point)

Confirm that the phase difference between the Z phase to the A phase is within ±25% during both forward and reverse run when one cycle of the A phase signal is calculated as100%. If the output signal waveform is not as shown below, refer to the next section "(8) Adjusting the Z phase and A phase difference" and adjust.

3. Setup

(8) Adjusting the Z phase and A phase difference

[1] Stop the motor, and make sure that the detection gears are not rotating. The sensor could be

damaged if adjustments are carried out while the gears are rotating. [2] Using a clearance gauge, adjust so that the gap between the sensor direction surface and the

detection gears’ circumference is 0.15±0.01mm, and loosen the sensor fixing screw. [3] The phase difference of the Z phase to the A phase can be adjusted by rotating the sensor as

shown on the right. At this time, rotate the sensor a little bit while using the marking lines on

the sensor and installation seat as a guide. [4] Tighten the sensor fixing screw so that the sensor

does not move, and confirm that the gap between the

sensor detection surface and detection gears'

circumference is 0.15 ± 0.01mm. Then, rotate the

gears and confirm the phase difference as explained

above. [5] When the phase difference is within the tolerable

range, apply a locking agent on the sensor fixing

screw, and then fix the sensor. Check the gap again

after fixing the sensor.

bit0. READY ON command (RDY)

1) This signal is input when the motor is ready to rotate. This is valid when the circuit between 1 pin (REDY) and 19 pin (CES1) of CN10 is closed (ON). When this signal is turned ON, the main circuit of the converter unit will be turned ON.

2) Before this signal is turned ON or within approx. one second from when this signal is turned ON till the "in READY ON" signal is turned ON, signals are not accepted even if turning the forward/reverse run command, orientation command ON.

3) If this signal is turned OFF during motor rotation, the current to the motor is shut OFF and the motor will coast to stop.

4) Turn this signal OFF for safety before the operator touches the spindle directly and attaches/removes the workpiece or tools. However, be careful not to turn this signal ON/OFF too frequently (100 times or more/day).

bit6. Parameter conversion command (PRM)

This is started when the spindle parameters are converted on the personal computer screen.

bit7. Drive unit alarm reset command (ALMR)

This turns ON while the alarm reset is input. Spindle alarms are reset. However, if this signal is turned ON during the motor rotation, the power supplied to the motor is shut off and the motor will coast to stop.
