Design Guide | VLT® AutomationDrive FC 360
Bit 02 = 1: Leads to ramping.
Bit 03, Coasting
Bit 03 = 0: The drive immediately releases the motor (the output transistors are shut off ), and it coasts to a standstill.
Bit 03 = 1: If the other starting conditions are met, the drive starts the motor.
In parameter 8-50 Coasting Select, define how bit 03 gates with the corresponding function on a digital input.
Bit 04, Quick stop
Bit 04 = 0: Makes the motor speed ramp down to stop (set in parameter 3-81 Quick Stop Ramp Time).
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 programmed to
[21] Speed up and [22] Speed down (parameter 5-10 Terminal 18 Digital Input to parameter 5-13 Terminal 29 Digital Input).
If freeze output is active, the drive can only be stopped in 1 of the following ways:
Bit 03 coast stop.
l
Bit 02 DC brake
l
Digital input programmed to [5] DC brake inverse, [2] Coast inverse, or [3] Coast and reset inv (parameter 5-10 Terminal 18
l
Digital Input to parameter 5-13 Terminal 29 Digital Input).
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: If the other starting conditions are met, bit 06 allows the drive to start the motor.
In parameter 8-53 Start Select, define how bit 06 ramp stop/start gates with the corresponding function on a digital input.
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.
Bit 08, Jog
Bit 08 = 1: Parameter 3-11 Jog Speed [Hz] determines the output frequency.
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 is active (parameter 3-51 Ramp 2 Ramp Up Time to parameter 3-52 Ramp 2 Ramp Down Time).
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.
Bit 11, Relay 01
Bit 11 = 0: Relay not activated.
