6.6.2. Output speed of maximum speed analog command
The relationship between the applied voltage of the speed analog command and the output speed
is described below.
Output speed of maximum analog voltage command
This value decides the output speed while the maximum permissible voltage is applied. If the
PC12 is 3000, the motor would rotate at 3000rpm when the applied voltage of speed command is 10V.
If the applied voltage of speed command is 5V, the rotary speed would be 1500rpm. The conversion is
listed as follows.
applied voltage of speed command
The output speed[rpm] = the setting value of PC12

6.6.3. Speed analog command smoothing
If the speed command changed violently, vibration or noise or even overshoot may be occurred by
the motor. Users could use related parameters for smoothing process to suppress those impacts. The
acceleration time constant could be used to adjust the slope of speed pattern from static state to the
speed command set by the user. The deceleration time constant could be used to adjust the slope from
the rotary state to the static state. The S-pattern acceleration/deceleration time constant could be used
to adjust the stability when starting or stopping the motor.
