Bit1 = This setting allows the frequency/torque commands of PU05 and RS485 to either
be retained or forgotten after power has been removed.
Bit2 = This setting allows the frequency/torque commands of the UP/DOWN external
terminals to either be retained or forgotten after power has been removed.
Bit3 = This setting allows the FWD/REV direction to either be retained or forgotten after
power has been removed.
Bit4 = This parameter does not have to be memorized into EEPROM; its original value
will be recovered after the power is turned back on.
Example: If the frequency is to be controlled by the UP/DOWN keys (bit 0 = 0) and the
frequency is to be retained after power off (bit 1 = 1) and the direction is also to
be retained (bit3=1) then Pr. 00-09 must be set to 01010.
00-10 Control Methods Factory setting 0
Settings 0 V/F Control
1 V/F Control + PG
2 Vector Control (open loop)
3 Vector Control + PG (closed loop)
4 Torque Control
5 Torque Control + PG
This parameter determines the control mode for the AC motor drive
0: V/F control: Drive will follow the V/F curve described by Pr. 01-00 to 01-08.
1: V/F control + PG: Drive will follow the V/F curve described by Pr. 01-00 to 01-08, but will
have more speed accuracy.
2: Vector Control: Enables Open Loop Vector control. To acquire the best results, it is
recommended to use the auto-tuning feature of the drive Pr. 05-00. By using this
feature, 200% rated torque may be obtained at 0.5Hz. For more open loop vector
control, refer to group 5 parameters. While in Vector Control, Pr. 01-03 to 01-08 and Pr.
05-04 are not used.
3: Vector control + PG: Enables the Closed Loop Flux Vector Control. The Closed Loop
Flux Vector Control will offer the highest torque and speed accuracy control. 200%
torque at 0Hz and a 1:1000 turn down ratio. While in Vector Control, Pr. 01-03 to 01-08
and Pr. 05-04 are not used.
