Look choises of parameter's Binary inputs [184] (page 17)
Quick stop
inactive
[823]
The condition for deactivation of Quick Stop, when selected signal is of numeric type
"value".

Start delay
[1238]
Delay between receiving START command and its execution. 0,000 s
0,000 s ÷
300,000 s
Stop delay
[1487]
Delay between receiving STOP command and its execution. 0,000 s
0,000 s ÷
300,000 s
STOP
timeout
[926]
Timeout for instantaneous tripping of the voltage after a STOP command and not
reaching the zero speed when the value of Stop type [836] (page 67) is "Ramp-
down" or "Step to 0" in vector control, or in V/f control when "Regenerative" is
selected in Max. current controller [352] (page 60).
30,0 s
0,0 s ÷
3600,0 s
In control modes when due to regenerative torque or current saturation after the STOP
command the decreasing of the frequency is not possible, the timer for this timeout is
increasing. If the speed does not decrease to 0 and the drive is stopped the normal way, the
inverter will trip the voltage even at non-zero speed.
7.4.3 FREQUENCY SETPOINT
Group of parameters number [7]
Setting of frequency setpoint of the converter.

Name [ID] Description Def.
Source of freq.
setpoint [706]
Setting the source of the frequency setpoint. AIN1
Value The source of the setpoint is fixed value.
Control panel The source of the setpoint are arrow keys in the MONITOR window in the control panel.
AIN1 The source of the setpoint is the corresponding analog input.
AIN2 The source of the setpoint is the corresponding analog input.
AIN3 The source of the setpoint is the corresponding analog input.
AIN4 The source of the setpoint is the corresponding analog input.
Discrete setpoints
The source of the setpoint are the discrete setpoint values [60] (page 54). It is not
possible to select this setting if the discrete setpoint speeds are assigned elsewhere (e.g.
Source of PC setpoint [130] (page 98)).
Up/down
commands
The source of the setpoint are the up/down commands, please see [970] (page 56).
Process controller The source of the setpoint is the process controller, please see [385] (page 97).
MODBUS
The source of the setpoint is the MODBUS serial communication, please see [658] (page
113).
PROFIBUS
The source of the setpoint is the PROFIBUS serial communication, please see [812]
(page 115).
Special The source of the setpoint is the special setting.
Maximal value The source of the setpoint is the maximum value of the quantity range.

Value depends on the parameter Freq. reverse source [195] (str. 51). For the choice
„ According to the setpoint value “ is from -( Max. frequency [111] (str. 69)), for other
choices is from Min. frequency [110] (str. 69).
Freq. reverse
source [195]
Setting the reverse source of the motor frequency setpoint. BIN6
Control panel Pressing the gray REVERSE button on the control panel causes the motor reverse.
No reverse The motor will always turn in a positive direction, it is the forward direction.
