Warning Interface for

the αi Spindle

Overview

For the αi spindle, the warning state can be reported before an alarm is

issued. When the warning state is entered, a report to the PMC is sent.

For example, this signal can be used for retracting tools or reducing

cutting load from the time a warning occurs by the time an overheat alarm

occurs. In addition, diagnostic information also contains warning

numbers.

[Classification]

Output

[Function]

Reports the warning number corresponding to the state of the αi spindle

amplifier.

[Output condition]

When the αi spindle is in the warning state, a warning number consisting

of SPWRN1 to SPWRN9 is output as nine-bit binary data.

If warnings occurred on multiple αi spindle amplifiers, the warning

number of the αi spindle having the smallest axis number is output.

However, when there is no αi spindle or the system configuration of the

spindle includes an additional spindle that is older than the αi spindle, this

function is invalid for all spindles.

The warning numbers and their descriptions are shown below.

time, use the PMC to perform processing as needed.

If the main circuit overheats, an alarm occurs.

If an open-phase is detected in the main power sup-

tected in the con-

ply, the warning signal is output. Since the spindle

About one minute (for the PSM) or about five se-

conds (for the PSMR) after the warning signal is out-

αi Spindle Information

Screen

General

In the αi spindle system, ID information output from each of the

connected units is obtained and output to the CNC screen.

The units that have ID information are shown below.

(Remark: Some instances of these units do not have ID information.)

S Spindle motor

S Spindle amplifier

S Power supply module

ID information is automatically read from each of the connected units

during first startup of the CNC and then recorded. During second or later

startup, the ID information recorded during first startup can be compared

with the ID information read this time on the screen to check whether the

configuration of the connected units is changed. (If there is a difference

between them, the alarm mark (*) appears.)

The recorded ID information can be edited. Therefore, the ID information

of an unit that does not have ID information can be displayed. (However,

the alarm mark (*) indicating a difference between these IDs appears.)

7.2.1.3

Tuning S analog voltage

(D/A converter)

(1) For M series, change the upper and lower limits as follows:

⋅ When gear change method A is used: Parameter 3736 = 4095,

parameter 3735 = 0

⋅ When gear change method B is used: Parameter 3751 = 4095,

parameter 3735 = 0

. For T series, these changes are not required.

(2) Tuning the D/A converter offset

Specify zero as the spindle speed. Then, by using a digital multimeter,

adjust the following parameter so that the voltage at the test pin DA2

on the spindle amplifier printed circuit board is 0 mV.

For M series

S0; (Specify the command by MDI operation, then press the cycle start button.)

For T series (in case of G-code system A)

G97 S0;

(Specify the command by MDI in the same manner as for M series.)

3731

Spindle speed (D/A converter) offset compensation value

(3) Tuning the D/A converter gain

Specify the maximum spindle speed of gear 1. Then, by using a digital

multimeter, adjust the following parameter so that the voltage at the

test pin DA2 on the spindle amplifier printed circuit board is 10.0 V.

For M series

Sxxxx ;

(xxxx is the value set in parameter 3741.)

(Specify the command by MDI operation, then press the cycle start button.)

3741

Max. spindle speed of gear 1 (1 to 9999) [min^-1]

For T series (in case of G-code system A)

G97 Sxxxx ;

(xxxx is the value set in parameter 3741.)

(Specify the command by MDI operation, then press the cycle start button.)

3741

Max. spindle speed of gear 1 (1 to 9999) [min^-1]

. Usually a voltage is output from the D/A converter by only

executing an S command. However, the clockwise rotation

command (M03) may be required on some machines.
