5.6.2 Explanation of the Control Bits
Bits 00/01
Bits 00 and 01 are used to choose between the four reference values, which are pre-programmed in par. 3-10 Preset Reference according to the following table:
Programmed ref. value Parameter Bit 01 Bit 02
1 3-10 [0] 0 0
2 3-10 [1] 0 1
3 3-10 [2] 1 0
4 3-10 [3] 1 1
NB!
In par. 8-56 Preset reference a selection is made to define how Bit 00/01 gates with the corresponding function on the digital inputs.
Bit 02, DC brake:
Bit 02 = “0” leads to DC braking and stop. Braking current and duration are set in par. 2-01 DC Brake current and 2-02 Braking time.
Bit 02 = “1” leads to ramping.
Bit 03, Coasting:
Bit 03 = “0” shuts off the output transistors causing the motor to coast to a standstill.
Bit 03 = “1” enables the frequency converter to start the motor if the other starting conditions have been fulfilled.
