Range of
Settings
0 - • The parameter directly sets in [r/min] timing to output zero speed detection
20000 output signal (WARN: CN X5 pin 12).
[50] You need to set parameter warning output selection (Pr09) to 1.
• The zero speed detection signal (WARN) will be output when the motor speed
falls below the set speed of this parameter Pr61.
• Setting of Pr61 acts on both CW and
CCW directions, irrespective of the
direction of motor rotation.
• There is hysteresis of 10 rpm. Set the
parameter 10 or more.
0 - • The parameter sets a detection level for determining excessive deviation of
32767 "protection against excessive position deviation" feature, by using the number
[1875] of retained pulses of the deviation counter.
• Calculate setting according to the expression shown below:
Level for Determining Excessive Position Deviation [PULSE]
Setting =
<Cautions>
Be careful because the protection against excessive position deviation may
work although there is no abnormality, in particular, when you not only set
position gain low but also set Pr63 low.
0 - 1 This parameter can disable the "protection against excessive position deviation"
function.
Setting
[0]
Disabled. The operation continues without causing abnormality
1
even when retained pulse exceeds the level for judgment set with
Pr63.
Runaway may occur if you make a mistake in the sequence of
phases of the motor or wiring of the encoder. Install a failsafe in
the device to prevent runaway.
0 - 2 The parameter sets the deceleration and stop operation after the overtravel inhibit
input (CCWL: Connector CNx58 pin or CWL: Connector CNx57 pin) activates and
becomes enabled.
Setting
Invalidate torque in the overtravel inhibit direction, and activate
[0]
the dynamic brake.
Invalidate torque in the overtravel inhibit direction, and have the
1
motor free run.
In the position control mode, servo lock is decelerated and
2
stopped, and in the internal velocity control mode, speed zero
clamp deceleration and stop is actuated.
