constant ② The bigger the setting value is, the higher the integral speed is and
the bigger the rigidity is. Parameter value is
determined by
specific servo unit model and load. Generally, the bigger the load
inertia， the smaller the setting value is.
③ Set the bigger value if there is no vibration for system.
PA 07 Torque instruction
filter
① Set cut-off frequency of low pass filter of torque instruction.
② It is used for limiting the frequency band of current instruction to get
the stable current response against the impact and vibration of the
current.
③ Set the bigger value if there is no vibration for system.
1-1500%
PA 08 Speed detecting low
pass filter constant
① Low pass filter cut-off frequency set for speed detection
② The smaller the setting value is and the lower the cut-off frequency
is, the lower the noise from motor is. If the load inertia is very large,
reduce the setting value properly. If the value is too small, vibration
may be caused by slow response.
③ The bigger the setting value is and the higher the cut-off frequency
is, the quicker the speed feedback response. If higher speed
response is
needed, the setting value can be increased
appropriately.

PA 09 Orientation
proportional gain
①Proportional gain set of orientation loop regulator
②he bigger the setting value is, the higher the gain is and the bigger the
rigidity is, the smaller the orientation lag is. But if the value is too big, the
vibration and overshoot may occur.
③The value is decided by special servo unit model and load.
1~1000/S
PA 10 Orientation
feedforward gain
① Feedforward gain set of orientation loop
② When it is set for 4096, it means that orientation lag is 0 in any
instruction pulse frequency.
③ If the feedforward gain of orientation loop increases and the high
response of the control system is raised, overshoot may occur for the
instability of the system orientation loop caused.
④Unless the high response is needed, the feedforward gain of
orientation loop is usually 0.

PA 11 Orientation
feedforward
instruction filter
coefficient
①Cut-off frequency determination of orientation
loop feedforward low
pass filter.
②The low pass filter is used for increasing the stability of complex
orientation control.
③The bigger the parameter value is and the higher the cut-off frequency
is, the more liable the noise and overshoot are to occur in running.
