P-18 (CP) Peak current
Data Range Default Unit Data type
Dependson motor model 1.5 A DEC
CM sets the peak (RMS) current setting of the servo drive. Peak current sets the maximum current that
should be used with a given motor. When the motor position requires more than the continuous value,
the peak current time calculation is done using I^2/T which integrates current values for more accurate
modeling of drive and motor heating. The servo drive will allow peak current for nor more than one
second. After one second of operation at peak current the current is reduced to the continuous current
setting (see CC command).
NOTE: In normal operation, please DONOT change this parameter.
NOTE: if you need to view or set this value on drive’s control panel P-18(CP), please refer to
following calculation:
LED display value =
x 100
Where
is target setting current, Unit for is A (amps)
P-20 (VM) Maximum velocity
Data Range Default Unit Data type
0.025~100 60 rps DEC
The maximum motor velocity in rev/sec. Used in all control modes to limit the maximum speed of the
drive.
NOTE: if you need to view or set this value on drive
’
s control panel P-20 (VM), please refer to
following calculation:
LED display value =
x 240
Where
is target velocity setting, Unit is rps (rev/sec).
P-21 (AM)
maximum acceleration/
deceleration
Data Range Default Unit Data type
0.167~5000 3000 rps/s DEC
The maximum acceleration/deceleration allowed. When the targeted acceleration/deceleration excels the
maximum value, the actual acceleration/deceleration will limit to the maximum value.
Also sets the deceleration rate used when an end-of-travel limit is activated during a move or when an
ST (Stop) or SK (Stop & Kill) command is sent.
NOTE: if you need to view or set this value on drive
’
s control panel P-21 (AM), please refer to
following calculation:
LED display value =
x 6
Where
is target maximum acceleration/deceleration setting, Unit is rps/s .
P-22 (JS) Jog velocity
Data Range Default Unit Data type
0.025~100 10 rps DEC
The speed for Jog moves in rev/sec.
NOTE:If you need to view or set this value on drive’s control panel P-22 (JS), please refer to
following calculation:
LED display value =
x 240
Where =
is target velocity setting, Unit is rps (rev/sec) .
P-23 (JA) Jog acceleration
Data Range Default Unit Data type
0.167~5000 100 rps/s DEC
The accel/decel rate for Jog moves and velocity control mode in rev/sec/sec. Setting JA overwrites the
