Increment Positioning
A relative move command from the current position
Interlock
The velocity override value is set to 0% internally.
Invalid
Invalid state. To not use a specific function in parameter settings, etc., set to invalid (0).
IPM fault signal
An error signal output by the IPM unit built in the power module
IPM fault signal
An error signal output by the IPM unit built in the power module
J
K
kpulse
Unit of pulses obtained by raising 10 to the third power
L
Linear Coordinate System
A coordinate system that manages coordinates within a range of -999999999 to 999999999
linearly. If this range is exceeded, a software EOT error occurs.
LM series
Linear motors
Load Inertia
The moment of inertia of load attached to the motor
Load Scale Factor
Load scale factor [K] = load inertia/rotor inertia
Logic I/O
A virtual I/O of firmware in the drive. Some of logic I/O are assigned to actual I/O (hard I/O).
Logic I/O Initial Value
Initial values (ON or OFF) at power-on start can be set up for logic I/O (inputs only). Setting
initial values to logic I/O actually assigned to hard I/O has no significance as they are
initialized to external commands at startup.
M
Machine Resonance
Since the DD motor directly drives load, the characteristics of the load may affect the control
system, causing oscillations. These oscillations include hunting and windup phenomenon at a
relatively low frequency (several Hz), an oscillation around a high frequency phase, and a
mechanical oscillation. To take appropriate countermeasures, it is necessary to know the
accurate resonance frequency.
Machine Setting Parameter
If these parameters are changed, the changes made take effect when the power is turned ON
next time (parameters starting from #110).
