8-1 Basic Parameters
Pn003
Realtime Autotuning Machine Rigidity Setting
Setting
0 to 31
range
 Default settings:
* Pn003 = 11 - For 200V drives of 1 kW or upper and 400V drives
 Set the machine rigidity to one of 32 levels when realtime autotuning is enabled.
 If the set value is changed suddenly by a large amount, the gain may change rapidly, subjecting
the machine to shock. Always start with a small setting, and gradually increase the setting while
monitoring machine operation.
Pn004
Inertia Ratio
Setting
0 to 10,000
range
 Set the load inertia as a percentage of the motor rotor inertia.
 Pn004 = (Load inertia / Rotor inertia) × 100%
 When realtime autotuning is enabled, the inertia ratio is continuously estimated and saved in
EEPROM every 30 minutes.
 If the inertia ratio is set correctly, the setting unit for the Speed Loop Gain (Pn101) and Speed Loop
Gain 2 (Pn106) is Hz.
If the Inertia Ratio (Pn004) is set larger than the actual value, the setting for speed loop gain will
8
increase. If the Inertia Ratio (Pn004) is set smaller than the actual value, the setting for speed loop
gain will decrease.
Pn005
Command Pulse Input Selection
Setting
0 or 1

 Selects whether to use photocoupler or input for line driver only for the command pulse input.
 When using a Servo Relay Unit cable, set to 0 (photocoupler input).
