P1 - 55
MSPD
Maximum Speed Limit
Address: 016EH, 016FH
Default: rated speed
Related Section: N/A
Applicable Control Mode: ALL
Unit: r/min
Range: 0 ~ Max. speed
Data Size: 16-bit
Display Format: Decimal
Settings:
This parameter is used to set maximum motor speed. The default setting is rated
speed.
P1 - 56
OVW
Output Overload Warning Time
Address: 0170H, 0171H
Default: 120
Related Section: N/A
Applicable Control Mode: ALL
Unit: %
Range: 0 ~ 120
Data Size: 16-bit
Display Format: Decimal
Settings:
This parameter is used to set output overload time. If the setting value of
parameter P1-56 is set to 0 ~ 100, the function of parameter P1-56 is enabled.
When the motor has reached the output overload time set by parameter P1-56, the
motor will send a warning to the drive. After the drive has detected the warning,
the DO signal OLW will be activated. If the setting value of parameter P1-56
exceeds 100, the function of parameter P1-56 is disabled.
tOL
= Permissible Time for Overload x the setting value of parameter P1-56
When overload accumulated time (continuously overload time) exceeds the value
of
tOL
, the overload warning signal will output, i.e. DO signal, OLW will be ON.
However, if the accumulated overload time (continuous overload time) exceeds the
permissible time for overload, the overload alarm (AL006) will occur.
For example:
If the setting value of parameter P1-56 (Output Overload Warning Time) is 60%,
when the permissible time for overload exceeds 8 seconds at 200% rated output,
the overload fault (AL006) will be detected and shown on the LED display.
At this time,
tOL
= 8 x 60% = 4.8 seconds
Result:
When the drive output is at 200% rated output and the drive is continuously
overloaded for 4.8 seconds, the overload warning signal will be ON, i.e. DO
signal OLW will be activated. If the drive is continuously overloaded for 8 seconds,
