Checking For What Keeps The Mcc From Being Switched On

(1) The system is still in an emergency stop status.

→ Check the connection to make sure that the emergency stop

signal connected to the PSM connector CX4 and the

emergency stop signal (such as *ESP) input to the CNC are

both released.

(2) There is a connector problem.

(a) No terminating connector is attached.

→ Check whether a terminating connector is attached to

JX1B of the SVM or SPM at the end of the connection

chain.

(b) The interface cable between JX1B of the power supply

module and JX1A of the SVM or SPM is defective.

→ Check whether the interface cable is faulty.

(3) The power for driving the magnetic contactor is not supplied.

→ Check the voltage across the both ends of the coil of the

magnetic contactor.

(4) The relay for driving the magnetic contactor is defective.

→ Check that a circuit between pins <1> and <3> of connector

START-UP PROCEDURE

(4) Observing the motor current

You can observe an instantaneous motor current value by

observing the voltage across a reference voltage (0 V) check pin

and a motor current check pin with an oscilloscope. Note that you

cannot use a device such as a multimeter to observe correct

values.

(Instantaneous motor current value) = (voltage at motor current

check pin) × (factor for calculating motor current)

Calculation example:

When the voltage at a motor current check pin is 3.2 V, and

the factor for calculation is 3 A/V:

Actual motor current (A) = 3.2 V × 3 A/V = 9.6 A

(4) Checking the power supply voltage

You can measure the voltage across a reference voltage (0V)

check pin and a power check pin with a multimeter, oscilloscope,

or the like to observe the power supply voltage for the control

circuit inside the servo amplifier. If the measured voltage is

within ±5% relative to the nominal voltage, the measured voltage

can be considered to be acceptable.

Checking The Feedback Signal Waveform

First, refer to Subsection 9.2.3 of "FANUC SERVO AMPLIFIER α

series Descriptions"

(B-65162E), and make sure that the spindle

sensors and other detectors are connected at the correct points. Next,

see the table given below to find the corresponding check terminal

names on the check board from the sensor connector connection points.

Do not observe feedback signals before the parameters for the detectors

that are set. Phase A, B, and Z signals may not be output correctly until

the parameters are loaded from the CNC.

4.3.4.4 High-resolution magnetic pulse coder

After mounting a high-resolution magnetic pulse coder on the machine,

check waveforms. If a measurement value exceeds the specified range,

adjustment is required.

After mounting the sensor, you should check waveforms before

installing components such as a pulley, drawbar, and brake to make

adjustment easier.
