P1 - 54
PER
Positioning Completed Width
Communication Addr.: 0136H
Default: 100
Applicable Control Mode: P
Range: 0~10000
Unit: pulse
This parameter is used to band of the target position.
For Example, at factory default TPOS (positioning completed signal) will activate once the motor
is in -99 pulses range of the target position, then deactivate after it r99 pulses range of
the desired position.
P1 - 55
MSPD
Maximum Speed Limit
Communication Addr.: 0137H
Default: rated speed
Applicable Control Mode: P/S/T
Range: 0~max. speed
Unit: rpm
This parameter is used to set maximum rotation speed. The default setting is rated speed.
P1 - 56
OLW
Output Overload Warning
Communication Addr.: 0138H
Default: 50
Applicable Control Mode: P/S/T
Range: 0~100
Unit: %
This parameter is used to set output overload level. When the motor has reached the output
overload level set by parameter P1-56, the motor will send a warning to the drive. After the drive
has detected the warning, the DI signal OLW will be activated.
t
OL
= 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 overload
accumulated time (continuously overload time) exceeds the permissible time for overload, the
overload alarm (ALE06) will occur.
For example:
If the setting value of parameter P1-56 (Overload Warning Level) is 60%, when the permissible
time for overload exceeds 8 seconds at 200% rated output, the overload fault (ALE06) will be
detected and shown on the LED display.
At this time,
t
OL
= 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, and the overload warning signal will be ON (DO code is 10, i.e. DO signal OLW will be
activated). If the drive is continuously overloaded for 8 seconds, the overload alarm will be
detected and shown on the LED display (ALE06). Then, Servo Fault signal will be ON (DO signal
ALRM will be activated)
