Drive Will Not Respond to Control Signals
- Danfoss Control Word profile
Check 1: Is the Control word valid?
If bit 10=0 in the Control word, then the drive will not accept the Control word, because the default
setting is bit 10=1. Set bit 10=1 via the PLC.
Check 2: Is the relationship between bits in the Control word and the terminal I/Os correct?
Check the logical relationship in the frequency converter.
Set the logic to bit 3=1 AND digital input=1 in order to achieve a successful start.
Define the desired logical relationship in par. 8-50 to 8-56 according to the following range of options.
Select the FC 300 control mode, digital input and/or bus communication, using par. 8-50 to 8-56.
The tables below show the effect upon the FC 300 of a coast command for the full range of par. 8-50
settings.
The effect of control mode upon the function of par. 8-50 Coasting select, 8-51 Quick stop select and
8-52 DC Brake select is as follows:
If Digital input [0] is selected, the terminal will
control the Coast and DC Brake functions.
Par. 8-50/51/52 setting: Digital input [0]
Terminal Bit 02/03/04 Function
0 0 Coast/DC brake/Q-Stop
0 1 Coast/DC brake/Q-Stop
1 0 No Coast/DC brake/Q-Stop
1 1 No Coast/DC brake/Q-Stop
If Bus [1] is selected, commands will be
activated only when given via the control word.
Par. 8-50/51/52 setting: Bus [1]
Terminal Bit 02/03/04 Function
0 0 Coast/DC brake/Q-Stop
0 1 No Coast/DC brake/Q-Stop
1 0 Coast/DC brake/Q-Stop
1 1 No Coast/DC brake/Q-Stop
If Logic AND [2] is selected, both signals must
be activated to perform the function.
Par. 8-50/51/52 setting: Logic AND [2]
Terminal Bit 02/03/04 Function
0 0 Coast/DC brake/Q-Stop
0 1 No Coast/DC brake/Q-Stop
1 0 No Coast/DC brake/Q-Stop
1 1 No Coast/DC brake/Q-Stop
If Logic OR [3] is selected, activation of one
signal will activate the function.
Par. 8-50/51/52 setting: Logic OR [3]
Terminal Bit 02/03/04 Function
0 0 Coast/DC brake/Q-Stop
0 1 Coast/DC brake/Q-Stop
1 0 Coast/DC brake/Q-Stop
1 1 No Coast/DC brake/Q-Stop
NB!:
Please note that Coasting, Quick Stop and DC brake functions are active for logic “0’’.
