P1025 Fixed frequency mode – Bit 4
Min: 1 Def: 1 Max: 3
Level 3
Enum:
1=Direct selection 2=Direct selection + ON command 3=Binary coded selection + ON command
Details:
See parameter P1001 for description of how to use fixed frequencies.
P1026[2] BI: Fixed freq. selection Bit 4
Min: 0:0 Def: 722:4 Max: 4000:0
Level 3
Index:
P1026[0] : IN000 (AUTO) 1st. Command data set (CDS) P1026[1] : IN001 (HAND 2nd. Command data set (CDS)
Dependency:
Accessible only if P0701-P0706=99 (function of digital inputs=BICO).
Details:
See P1020 (fixed frequency selection Bit 0) for most common settings.
P1027 Fixed frequency mode – Bit 5
Min: 1 Def: 1 Max: 3
Level 3
Enum:
1=Direct selection 2=Direct selection + ON command 3=Binary coded selection + ON command
Details:
See parameter P1001 for description of how to use fixed frequencies.
P1028[2] BI: Fixed freq. selection Bit 5
Min: 0:0 Def: 722:5 Max: 4000:0
Level 3
Index:
P1028[0] : IN000 (AUTO) 1st. Command data set (CDS) P1028[1] : IN001 (HAND) 2nd. Command data set (CDS)
Dependency:
Accessible only if P0701-P0706=99 (function of digital inputs=BICO).
Details:
See P1020 (fixed frequency selection Bit 0) for most common settings.
P1031 Setpoint memory of the MOP
Min: 0 Def: 0 Max: 1
Level 2
Enum:
0=PID-MOP setpoint will not be stored 1=PID-MOP setpoint will be stored (P2240 is updated)
Note:
On next ON command, motor potentiometer setpoint will be the saved value in parameter P1040 (setpoint of the MOP).
P1032 Inhibit reverse direction of MOP
Min: 0 Def: 1 Max: 1
Level 2
Enum:
0=Reserve direction is allowed 1=Reserve direction inhibited
Dependency:
Motor potentiometer (P1040) must be chosen as main setpoint or additional setpoint (using P1000).
Note:
It is possible to change motor direction using the motor potentiometer setpoint (increase/decrease frequency either by
using digital inputs or BOP/AOP keypad up/down).
P1040 Setpoint of the MOP
Min: -650.00 Def: 5.00 Max: 650.00
Level 2
Note:
If motor potentiometer setpoint is selected either as main setpoint or additional setpoint, the reverse direction will be
inhibited by default of P1032 (inhibit reverse direction of MOP). To re-enable reverse direction, set P1032=0.
r1050 CO: Act. Output freq. of the MOP
Min: - Def: - Max: -
Level 3
r1078 CO: Total frequency setpoint
Min: - Def: - Max: -
Level 3
P1080 Min. Frequency
Min: 0.00 Def: 0.00 Max: 650.00
Level 1
Note:
Value set here is valid both for clockwise and for anticlockwise rotation.
Under certain conditions (for example, ramping, current limiting), motor can run below minimum frequency.
P1082 Max. Frequency
Min: 0.00 Def: 50.00 Max: 650.00
Level 1
Dependency:
Limited internally to 200 Hz or 5 * rated motor frequency (P0305) when P1300 >= 20 (control mode=vector control). The
value is displayed in r0209 (maximum frequency).
Note:
The value set here is valid for both clockwise and counterclockwise rotation.
The maximum output frequency of inverter can be exceeded if one of the following is active:
Slip compensation=f
max
+ f
slip comp max
, or
Flying restart=f
max
+ f
slip nom
Maximum motor speed is subject to mechanical limitations.
