MHT258a (Engl.)9-11
(e) Cont (control signal) error
• Touch panel display
• Detection (example)
Several control input signal (CONTn) terminals on CN1 of amplifier are assigned to the same signal.
• Cause, check and remedy
RYS □□□S3-VVS type amplifier : System para. 1 to 8 have the same set value.
RYS □□□S3-VSS type amplifier : System para. 1 to 5 have the same set value.
Since several terminals cannot be assigned to the same signal, any one setting should be selected. Forced stop (10), free run (54), external
fault input (34) and not specified (0) may be present on several terminals. Several control output terminals can be assigned to the same
signal.
Remark : “Cont error” does not occur in case of [CONT] assign valid at all times 1 (2) by system para. 87 and 88, and overlap setting of
system para. 1 to 8.
A signal set as [CONT] assign valid at all times is valid at all times.
Do not position the interrupt input (49) to [CONT1 to 8]. If they are positioned to [CONT9 to 13], the “Cont error” is detected.
(f) Low voltage, undervoltage
• Touch panel display
• Detection (example)
The voltage supplied to the amplifier is below the minimum specified level.
• Cause, check and remedy
The supply voltage may have dropped on account of momentary failure, etc. or the power supply capacity may be poor.
Remark : The detection of undervoltage can be invalidated by setting of system para. 85.
If, in this case, free run is selected by setting of system para. 84, the running can be continued at momentary failure.
