List of the possible functions of the digital inputs P420 ... P425, P470
Value Function Description Signal
00 No function Input switched off. ---
01 Enable right The FI delivers an output signal with the rotation field right if a
positive setpoint is present. 0
→ 1 Flank (P428 = 0)
High
02 Enable left The FI delivers an output signal with the rotation field left if a
positive setpoint is present. 0
→ 1 Flank (P428 = 0)
High
If automatic starting is active (P428 = 1), a high level is sufficient.
If the functions "Enable right" and "Enable left" are actuated simultaneously, the FI is blocked.
03 Change rotation direction Causes the rotation field to change direction, combined with
Enable right or left. High
04 Fixed frequency 1 1 The frequency from P429 is added to the actual setpoint
value. High
05 Fixed frequency 2 1 The frequency from P430 is added to the actual setpoint
value. High
06 Fixed frequency 3 1 The frequency from P431 is added to the actual setpoint
value. High
07 Fixed frequency 4 1 The frequency from P432 is added to the actual setpoint
value. High
If several fixed frequencies are actuated at the same time, then they are added with the correct sign. In addition,
the analog setpoint (P400) and possibly the minimum frequency (P104) are added.
08 Parameter set switch Bit 0 Selection of the active parameter set. (Low level = Parameter
set 1, high level = Parameter set 2) High
09 Hold frequency During the acceleration or deceleration phase, a low level will
cause the actual output frequency to be "held". A high level
allows the ramp to proceed. Low
10 Voltage disable 2 The FI output voltage is switched off and the motor runs freely
to a stop (low = blocked). Low
11 Quick stop 2 The FI reduces the frequency according to the programmed
quick stop time (P426). Low
12 Fault acknowledgement 2 Fault acknowledgement with an external signal. If this function
is not programmed, an fault can also be acknowledged by a
low enable setting (P506). 0 Æ 1
flank
13 PTC resistor input 2 Analog evaluation of signal present. Switching threshold at
approx. 2.5 V Switch-off delay = 2sec, warning after 1sec. Analog
14 Remote control 2 With Bus system control, low level switches the control to
control via control terminals. High
15 Jog frequency 1 The fixed frequency value can be adjusted using the
HIGHER/LOWER and ENTER keys (P113), if control is via
the ControlBox or ParameterBox. High
16 Motor potentiometer As in setting 09, however, the frequency is not maintained
below the minimum frequency P104 and above the maximum
frequency P105. The ramps can be set using start-up and
braking time. Low
17 Reserved
18 Watchdog 2 Input must see a high flank cyclically (P460), otherwise error
E012 will cause a shutdown. Function starts with the 1st high
flank.
0 Æ 1
flank
19 Setpoint 1 on/off Analog input switch-on and switch-off 1/2 (high = ON) The low
signal sets the analog input to 0% which does not lead to
shutdown when the minimum frequency (P104) > than the
absolute minimum frequency (P505).
High
20 Setpoint 2 on/off
21 Fixed frequency 5 1 The frequency from P433 is added to the actual setpoint value. High
