OT 032 NEED ZRN (ABS PCDR) The counter value of the absolute pulse coder does not match the
machine coordinates.
Axis type
OT 034 BATTERY ZERO
(ABS PCDR)
The battery voltage of the absolute pulse coder is 0 V. Check
whether the battery is connected properly. If the battery is con-
nected properly, replace it.
Axis type
O T036 BATTERY DOWN (SPLC) The battery voltage of the serial pulse coder is low. (Built–in unit)
O T037 BATTERY DOWN (EX) The battery voltage of the additional detector is low.
(Separate unit)
O T038 BATTERY ZERO (SPLC) The serial pulse coder battery voltage is 0 V. (Built–in unit)
O T039 BATTERY ZERO (EX) The serial pulse coder battery voltage is 0 V. (Separate unit)
OT 100 SPINDLE ALARM The spindle motor alarm was generated, but the code for specify-
ing the cause of the alarm is 0.
OT 101 SPINDLE MOTOR
OVERHEAT
The spindle motor overheated.
OT 102 EXCESS VELOCITY
ERROR
The difference between the speed set for the spindle motor and
the actual speed of the spindle motor was too great (15% to 20%).
OT 103 FUSE F7 BLEW Fuse F7 for the speed control unit of the spindle motor has blown.
OT 104 FUSE F1, F2 OR F3 BLEW Fuse F1, F2, or F3 for the speed control unit of the spindle motor
has blown.
OT 105 FUSE AF2 OR AF3 BLEW Fuse AF2 or AF3 for the speed control unit of the spindle motor
has blown.
OT 106 EXCESS VELOCITY
(ANALOG)
The speed of the spindle motor exceeded the maximum rating
(analog detection).
OT 107 EXCESS VELOCITY
(DIGITAL)
The speed of the spindle motor exceeded the maximum rating
(digital detection).
OT 108 VOLTAGE (+24V) TOO
HIGH
The voltage of the 24 V power supply for the speed control unit of
the spindle is too high.
OT 109 POWER SEMICONDUCTOR
OVERLOAD
The power semiconductor overheated.
OT 110 VOLTAGE (+15) TOO LOW The voltage of the 15 V power supply for the speed control unit of
the spindle motor is too low.
OT 111 VOLTAGE EXCESS
(DC LINK)
The voltage in the DC link for the speed control unit of the spindle
motor is too high.
OT 112 CURRENT EXCESS
(DC LINK)
The current in the DC link for the speed control unit of the spindle
motor is excessive.
OT 113 CPU ERROR The CPU or a peripheral circuit of the speed control unit of the
spindle motor is faulty.
OT 114 ROM ERROR The ROM of the speed control unit of the spindle motor is faulty.
OT 115 OPTION ALARM Optional alarm for the spindle motor.
OT 116 DISCONNECTION POS
CODER
The position coder is disconnected.
OT 117 SPINDLE OVERHEAT Spindle alarm was detected by the function for detecting fluctua-
tions in spindle speed.
OT 120 UNASSIGNED ADDRESS
(HIGH)
The upper four bits (EIA4 to EIA7) of an external data I/O interface
address signal are set to an undefined address (high bits).
OT 121 UNASSIGNED ADDRESS
(LOW)
The lower four bits (EIA0 to EIA3) of an external data I/O interface
address signal are set to an undefined address (low bits).
OT 122 TOO MANY MESSAGES Requests were made to display more than four external operator
messages or external alarm messages at the same time.
OT 123 MESSAGE NUMBER NOT
FOUND
An external operator message or external alarm message cannot
be cancelled because no message number is specified.
