larm detected
(3) Faults with alarm indication
If an alarm is detected, the detected contents are displayed on the touch panel of amplifier.
If multiple alarms are detected simultaneously, light-up occurs in accordance with the priority order given below.
Priority order Display Description
1 System error
2 Overcurrent, output overcurrent
3 Overspeed
4 Low voltage, undervoltage
5 High voltage, overvoltage
6 Encoder trouble
7 Circuit trouble, amplifier trouble
8 Data error, memory error
9 Combination error
10 Resistor heat 2
11 Encoder communication error
12 Cont (control signal) error
13 Over load, motor overheat
14 Amp heat, amplifier overheat
15 Resistor heat, baking (OB) resistor overheat
16 Over flow, deviation excessive
17 Encoder heat, encoder overheat
18 Absolute data lost
19 Absolute data over flow
20 Terminal error
21 (non)
(*1) 1[sec] min.
Remark : An alarm is displayed if detected.
If, at a displayed status, the alarm detection is reset by a control input signal, the initial screen (system para. 89 setting) appears.
The alarm detection can be reset in the test running mode [Fn004] also.
Holding down the ∧ key and ∨ key simultaneously for at least 1[sec] at a status where an alarm detection is displayed resets
the alarm detection.
