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
