D Identification of disconnection alarms and overload alarms
Disconnection alarms and overload alarms can be identified as shown
in the following table by the diagnostic data 3014 and 3015.
Alarm type 3014#7
OVL
3014#1
FBAL
3015#7
ALDF

EXPC
Overheat 1 0 1 0
Amplifier overheat 1 0 0 0
Disconnection (hardware) of built–in
pulse coder
0 1 1 0
Disconnection (hardware) of sepa-
rate pulse coder

If an SV101 data error alarm (ABS PCDR) or an OT032 reference
position return alarm (ABS PCDR) is generated, the contents of the alarm
are indicated.

(The subsequent axes correspond to data numbers each increased by 20
in that order.)
Bit Name Internal state when “1” is indicated
#0 APNZRN The reference position does not correspond to the
value of the absolute–position detection counter.
(Action: Make correspondence between the
reference position and the absolute–position
detection.)
#1 APPLSM A pulse error alarm was generated. (Action: Make
correspondence between the reference position
and the absolute–position detection.)
#2 APBATZ The battery voltage of the absolute–position
detector became 0. (Action: Replace the battery
and make correspondence between the reference
position and the absolute–position detection.)
#3 APCER A communication error occurred during data
transmission. (Action: Replace the pulse coder.)
#4 APTER A time over error occurred during data
transmission. (Action: Replace the pulse coder.)
#5 APFER A framing error occurred during data
transmission. (Action: Replace the pulse coder.)
#6 APPER A parity error occurred during data transmission.
(Action: Replace the pulse coder.)
