P436
[-01]
[-02]
Dig. out. hysteresis
(Hysteresis of digital outputs)
S
1 ... 100 %
{ 10 } [-01] = Digital output 1, Digital output 1 of the frequency inverter
[-02] = Digital output 2, Digital output 2 of the frequency inverter
Difference between switch-on and switch-off point to prevent oscillation of the output signal.
P460
Time Watchdog
(Time Watchdog)
S
-250.0 ... 250.0 sec
{ 10.0 } 0.1 ... 250.0 = The time interval between the expected Watchdog signals (programmable function
of the digital inputs P420…). If this time interval elapses without a pulse being
registered, switch off and error message E012 are actuated.
0.0 = customer error:
As soon as a high-low flank or a low signal is detected at a digital input
(function 18) the FI switches off with error message E012.
-250.0 … -0.1 = Rotor running watchdog: In this setting the rotor running watchdog is active.
The time is defined by the number of the value which has been set. When the FI is
switched off, there is no watchdog message. After each enable, a pulse must first
be received before the watchdog is activated.
P464 Fixed frequencies mode
(Fixed frequencies mode)
S
0 ... 1
{ 0 } This parameter determines the form in which fixed frequencies are to be processed.
0 = Addition to main setpoint: Fixed frequencies and the fixed frequency array are added to
each other. I.e. they are added together, or added to an analog setpoint to which limits are
assigned according to P104 and P105.
1 = Main setpoint: Fixed frequencies are not added - neither together, nor to analog setpoints.
If for example, a fixed frequency is switched to an existing analog setpoint, the analog
setpoint will no longer be considered.
Programmed frequency addition or subtraction with an analog input value or a bus setpoint
is still possible and valid, as is the addition to the setpoint of a motor potentiometer function
(function of digital inputs: 71/72)
If several fixed frequencies are selected simultaneously, the frequency with the highest value
has priority (E.g.: 20>10 or 20>-30).
Note:
The highest active fixed frequency is added to the setpoint value of the motor potentiometer
if the functions 71 or 72 are selected for 2 digital inputs.
