Dependency: Related parameter: P1074 (BI: Disable additional setpoint)
Caution: Changing this parameter sets (to default) all settings on item selected. These are the following parameters:
P1070, P1071, P1075, P1076
If P1000 = 1 or 1X, and P1032 (inhibit reverse direction of MOP) = 1, then reverse motor direction will be
inhibited.
Note: RS485 also supports MODBUS protocol as well as USS. All USS options on RS485 are also applicable to
MODBUS.

10.00 U, T - DDS Float 2
Defines fixed frequency setpoint 1. There are 2 types of fixed frequencies:
1. Direct selection (P1016 = 1):
– In this mode of operation 1 Fixed Frequency selector (P1020...P1023) selects 1 fixed frequency.
– If several inputs are active together, the selected frequencies are summed. E.g.: FF1 + FF2 + FF3
+ FF4.
2. Binary coded selection (P1016 = 2):
– Up to 16 different fixed frequency values can be selected using this method.
Dependency: Select fixed frequency operation (using P1000).
Inverter requires ON command to start in the case of direct selection. Therefore r1025 must be connected
to P0840 to start.
Note: Fixed frequencies can be selected using the digital inputs.
