8.11.2.5 Bit 05, Hold Output Frequency
Bit 05 = 0: The present output frequency (in Hz) freezes. Change the frozen output frequency only with the digital inputs program-
med to [21] Speed up and [22] Speed down (parameter 5-10 Terminal 18 Digital Input to parameter 5-13 Terminal 29 Digital Input).
N O T I C E
If freeze output is active, the drive can only be stopped in 1 of the following ways:
Bit 03 coast stop.
Bit 02 DC brake.
Digital input programmed to [5] DC brake inverse, [2] Coast inverse, or [3] Coast and reset inv (parameter 5-10 Terminal 18 Digital
Input to parameter 5-13 Terminal 29 Digital Input).
8.11.2.6 Bit 06, Ramp Stop/Start
Bit 06 = 0: Causes a stop and makes the motor speed ramp down to stop via the selected ramp-down parameter.
Bit 06 = 1: Allows the drive to start the motor if the other starting conditions are met.
In parameter 8-53 Start Select, define how bit 06 ramp stop/start gates with the corresponding function on a digital input.
8.11.2.7 Bit 07, Reset
Bit 07 = 0: No reset.
Bit 07 = 1: Resets a trip. Reset is activated on the leading signal edge, that is, when changing from logic 0 to logic 1.
8.11.2.8 Bit 08, Jog
Bit 08 = 1: Parameter 3-11 Jog Speed [Hz] determines the output frequency.
8.11.2.9 Bit 09, Selection of Ramp 1/2
Bit 09 = 0: Ramp 1 is active (parameter 3-41 Ramp 1 Ramp Up Time to parameter 3-42 Ramp 1 Ramp Down Time).
Bit 09 = 1: Ramp 2 (parameter 3-51 Ramp 2 Ramp Up Time to parameter 3-52 Ramp 2 Ramp Down Time) is active.
8.11.2.10 Bit 10, Data Not Valid/Data Valid
Tell the drive whether to use or ignore the control word.
Bit 10 = 0: The control word is ignored.
Bit 10 = 1: The control word is used. This function is relevant because the telegram always contains the control word, regardless of
the telegram type. If the control word is not needed when updating or reading parameter, turn it off.
8.11.2.11 Bit 11, Relay 01
Bit 11 = 0: Relay 01 not activated.
Bit 11 = 1: Relay 01 activated if [36] Control word bit 11 is selected in parameter 5-40 Function Relay.
8.11.2.12 Bit 12, Relay 02
Bit 12 = 0: Relay 02 is not activated.
Bit 12 = 1: Relay 02 is activated if [37] Control word bit 12 is selected in parameter 5-40 Function Relay.
8.11.2.13 Bit 13, Set-up Selection
Use bit 13 to select from the 2 set-ups according to the following table.
The function is only possible when [9] Multi set-ups is selected in parameter 0-10 Active Set-up.
