Setting Explanation
Sets the detection width for the speed conformity detection
(VCMP) signal.
Speed conformity is achieved when the absolute value of the dif-
ference between the internal speed command (before acceleration
and deceleration limits are applied) and the Servomotor speed is
less than the set speed.
Note This setting has a hysteresis of 10 r/min.
Sets the threshold level for the speed reached (TGON) signal.
Speed reached is determined when the absolute value of the Ser-
vomotor speed is greater than the setting speed.
Note Speed reached detection has a hysteresis of 10 r/min.
Sets the positioning completion range when Positioning Comple-
tion 2 (INP2) is selected.
Positioning is complete when the absolute value of the position
deviation converted into command units is less than this setting,
regardless of whether position command pulses are still being pro-
cessed.
Enables or disables the offset component readjustment function of
the Motor Phase Current Detector (CT) for Servo ON command
inputs. The readjustment is made when control power is turned
ON.
Note This adjustment is inaccurate if the offset is measured
while the Servomotor is rotating. To enable this function,
do not rotate the Servomotor when inputting the Servo ON
command.
0 Disabled (only when turning ON control power)
1 Enabled (when turning ON control power, or at Servo
ON)
Selects whether to activate the main power supply undervoltage
function (alarm code 13) when the main power supply is inter-
rupted for the duration of the Momentary Hold Time (Pn06D) dur-
ing Servo ON.
0 Turns the Servo OFF according to the setting for
the Stop Selection with Main Power OFF (Pn067),
interrupting the positioning command generation
process (positioning operation) within the Servo
Drive. When the main power supply is turned back
ON, Servo ON will resume. Restart the positioning
operation after performing the positioning operation
and recovering from Servo OFF.
1 Causes an error due to main power supply
undervoltage (alarm code 13).
This parameter is disabled if Pn06D = 1,000.
If Pn06D is set too long and the voltage between
P and N in the main power supply converter drops
below the specified value before a main power
supply interruption is detected, a main power
supply undervoltage (alarm code 13) will occur.
