6.3 EXTENDED FUNCTION PARAMETER LIST
Setting "1" in Pr. 30 "extended function display selection" makes the extended function
parameters valid. (Refer to the separately available instruction manual (detailed).)

For parameters 0 to 9, refer to the basic function parameters.
10
DC injection brake
operation frequency
3Hz
11
DC injection brake
operation time
0.5s
12
DC injection brake
voltage
Set the timing of switching to DC injection
brake (0 to 120Hz), the time to apply DC
injection brake (0 to 10s), and the braking
torque at DC injection brake start (0 to 15%).
(Set Pr. 12 to 4% when a constant-torque
motor is used.)
6%
13 Starting frequency
Frequency which is output by the inverter first
at a start and gives great influence to the
starting torque. About 1 to 3Hz for vertical lift
applications, or up to 5Hz to the maximum. For
other than vertical lift applications, factory
setting of about 0.5Hz is recommended.
0 to 60Hz
0.5Hz
14
Load pattern
selection
Choose the output frequency and output voltage
patterns according to the application (load
characteristic).
0: For constant-torque loads (when relatively large
torque is needed at low to high speeds)
1: For variable-torque loads (for applications
where torque is small at low speed, e.g. fans
and pumps)
2: For vertical lifts (for elevators at reverse rotation
boost of 0%)
3: For vertical lifts (for elevators at forward rotation
boost of 0%)
0
15 Jog frequency 5Hz
16
Jog acceleration/
deceleration time
Speed command (0 to 120Hz) and
acceleration/deceleration slope (0 to 999s) for
jog (inching) operation
0.5s
17
RUN key rotation
direction selection
The
RUN
key of the operation panel can be used
to choose the direction of rotation for operation.
0: forward rotation, 1: reverse rotation
0
19
Base frequency
voltage
Indicates the magnitude of the output voltage at
the base frequency (Pr. 3).
888: 95% of power supply voltage
- - -: Same as power supply voltage
0 to 500V, 888, - - -
- - -
<888>
20
Acceleration/
deceleration
reference frequency
Indicates the frequency to be referenced for
acceleration from or deceleration to 0Hz in the
time set in Pr. 7 "acceleration time" or Pr. 8
"deceleration time".
1 to 120Hz
60Hz
<50Hz>
