External frequency start pattern setting
External frequency sampling count setting
• The frequency scaling for the analog input signal (4-
20mA or 0-10V) is adjusted as follows.
: The scaling start frequency is set.
: The scaling end frequency is set.
: The analog input level for the scaling start
frequency is set.
: The analog input level for the scaling end frequency
is set.
• sets the frequency output start method.

Output frequency
• sets the number of sampling times (1-8 times) of the
analog input filter.
The average value sampled is used to determine the
command frequency.
Reduce the sample number to increase response time.
Increase the sample number to filter out noisy signals.
Multispeed frequency setting
- Multispeed frequency setting
• A maximum of 16 multispeed operation is possible when
multispeed frequencies are set in - .
(Input
terminals are set with C01-C06.)
∗ Multispeed 1 through 15 can
always be activated. However,
Multispeed 0 can only be
activated when A01 is
programmed to 02.
∗ Additionally, A20 through A35
can be programmed using F01
when each corresponding
speed is activated.
∗ Setting during operation is
possible.
Jogging operation setting
Jogging frequency setting
Jogging stop mode selection
• Use motor jogging operation for simple positioning. Assign
jogging to any of the input terminals FR through RST.
• The operation after jogging can
be selected from among "Free-
run stop," "Deceleration stop,"
and "DC braking stop."

Torque boost setting
Torque boost mode selection
Manual torque boost setting
Manual torque boost frequency adjustment
• The output voltage is raised in the low-frequency band to
adjust the motor torque. permits selection of
Manual/Auto for torque boost.
• When the torque boost is set to Manual, the torque boost
level and the boost frequency can be set.
