7n33 SPN_n_ : SHORTAGE
POWER
CHARGE
AL–33 Insufficient DC
link section
charging
Detects insufficient charging
of direct current power supply
voltage in power circuit sec-
tion when magnetic contactor
in amplifier is turned on (such
as open phase and defectifve
charging resistor).
Remove cause, then reset
alarm.
7n34 SPN_n_ : PARAMETER
SETTING
ERROR
AL–34 Parameter
data setting
beyond allow-
able range of
values
Detects parameter data set
beyond allowable range of
values.
Set correct data.
7n35 SPN_n_ : EX SETTING
GEAR RATIO
AL–35 Excessive
gear ratio data
setting
Detects gear ratio data set
beyond allowable range of
values.
Set correct data.
7n36 SPN_n_ : OVERFLOW
ERROR
COUNTER
AL–36 Error counter
overflow
Detects error counter over-
flow.
Correct cause, then reset
alarm.
7n37 SPN_n_ : SPEED
DETECT PAR.
ERROR
AL–37 Speed detec-
tor parameter
setting error
Detects incorrect setting of
parameter for number of
speed detection pulses.
Set correct data.
7n41 SPN_n_ : 1–ROT
POS–CODER
ERROR
AL–41 Alarm for indi-
cating failure
in detecting
position coder
1–rotaion sig-
nal.
Detects failure in detecting
position coder 1–rotation sig-
nal.
Make signal adjustment
for signal conversion cir-
cuit.
Check cable shield status.
7n42 SPN_n_ : NO 1–ROT.
POS–CODER
DETECT
AL–42 Alarm for indi-
cating position
coder 1–rota-
tion signal not
detected
Detects that position coder
1–rotation signal has not is-
sued.
Make 1–rotation signal ad-
justment for signal conver-
sion circuit.
7n43 SPN_n_ : DISCON. PC
FOR DIF. SP.
MOD.
AL–43 Alarm for indi-
cating discon-
nection of
position coder
signal for dif-
ferential speed
mode
Detects that main spindle
position coder signal used for
differential speed mode is not
connected yet (or is discon-
nected).
Check that main spindle
position coder signal is
connected to connector
CN12.
7n44 SPN_n_ : CONTROL
CIRCUIT(AD)
ERROR
AL–44 Control circuit
error (A/D con-
verter)
Detects an error in the A/D
converter.
Replace the printed circuit
board of the A/D
converter.
7n46 SPN_n_ : SCREW
1–ROT
POS–COD.
ALARM
AL–46 Alarm for indi-
cating failure
in detecting
position coder
1–rotation sig-
nal in thread
cutting opera-
tion.
Detects failure in detecting
position coder 1–rotation sig-
nasl in thread cutting opera-
tion.
Make 1–rotation signal ad-
justment for signal conver-
sion circuit.
Check cable shield status.
