Power Failure Detection Delay Time
[PFDDLY]
Control power reactivation after setting Setting range Unit Standard value
20 to 1000 ms 32
■
Sets the delay time from Control power OFF to Control power error detection.
The larger value makes the detection of Instantaneous stop slower.
(Control power holding time is about 100msec
Larger set value will only result in slower detections of errors. In case of power failure of Internal
logic circuit, operation is same as when Control power is turned ON again. In case of energy
shortage of Main circuit power, other errors such as Main circuit power loss may be detected.)
In this setting, actual detection delay time varies by -12ms to +6ms.
20
Excessive Deviation Warning Level
[OFWLV]
Setting range Unit Standard value
1 to 2147483647 Pulse 2147483647
■
Sets Warning output level before Excessive position deviation alarm is output.
◆ Sets at Encoder pulse resolution regardless of Electronic gear.
21
Deviation Counter Overflow Value
[OFLV]
Setting range Unit Standard value
1 to 2147483647 Pulse 5000000
■
Sets Position deviation value regarded as Excessive position deviation alarm.
◆
Sets at Encoder pulse resolution regardless of Electronic gear.
22
Overload Warning Level
[OLWLV]
Control power reactivation after setting Setting range Unit Standard value
20 to 100 % 90
■
Sets Warning output level before Overload alarm output.
◆
The possible level to be set is from 20%-99%, assuming that the Overload Warning
Level is 100%. When set to 100%, Overload warning and Overload alarm are output at
one time.
◆ Overload detection is assumed and set as 75%, of a rated load when Control power is
turned ON (hot start). Therefore, Overload warning may be output when Control power
is turned ON.
23
Velocity Feedback Alarm (ALM_C3) Detection
[VFBALM]
Setting range Unit Standard value
00 to 01 - 01:Enabled
■
Selects Valid/Invalid Velocity feedback error detection.
Selection Contents
00 Disabled Invalid
01 Enabled Valid
24
Velocity Control Alarm (ALM_C2) Detection
[VCALM]
Setting range Unit Standard value
00 to 01 - 00:Disabled
■
Selects Valid/Invalid Velocity control error detection.
Selection Contents
00 Disabled Invalid
01 Enabled Valid
◆ In such an operation pattern as causing a motor overshoot to the command, Velocity
control error may be detected by mistake. For this, set this parameter to invalid.
