In the case of multi-speed operation, when this signal is valid, the target frequency will be switched
to the jogging frequency.
41: Command switching to operation panel
In stop state, when this signal is valid, the command will be controlled by the panel reference.
42: Command switching to terminal
In stop state, when this signal is valid, the command will be controlled by the terminal reference.
43: Command switching to Modbus communication
In stop state, when this signal is valid, the command will be controlled by the Modbus reference.
44: Open-loop main and auxiliary switching
When this signal is valid, the velocity channel source is controlled by the open loop auxiliary
reference, i.e. P10.03 velocity channel option is controlled by the P50.00 reference.
45: PID main preset switching to internal
When this signal is valid, main reference channel under the process closed loop control is controlled
by the digital internal reference, otherwise it will not switch.
46: PID main preset switching to analog A0
When this signal is valid, main reference channel under the process closed loop control is switched
to A0, otherwise it will not switch.
47: PID auxiliary preset switching to invalid
When this signal is valid, control auxiliary reference channel under the process closed loop is invalid,
otherwise it will not switch.
48: PID auxiliary preset switching to analog A0
When this signal is valid, auxiliary reference channel under the process closed loop control is
controlled by the A0, otherwise it will not switch.
49: FJOG instruction (jog forward instruction)
When this signal is valid, it will run in forward rotation with the jogging frequency as the target
frequency; if the signal is invalid, it will stop running.
50: RJOG instruction (jog reverse instruction)
When this signal is valid, it will run in reverse rotation with the jogging frequency as the target
frequency; if the signal is invalid, it will stop running.
51: PID main preset switching to analog A1
When this signal is valid, main reference channel under the process closed loop control is switched
to A1, otherwise it will not switch.
52: PID auxiliary preset switching to analog A1
When this signal is valid, auxiliary reference channel under the process closed loop control is
controlled by the A1, otherwise it will not switch.
Note: add 100 to negate the signal, for example: 7: Terminal forward input (FWD), the forward
signal is valid when turned on. The inverter stops when the signal turns off. The forward signal is
valid when 107 signal disconnects. The inverter stops when the signal turns on.
Digital input filtering times
(times)
The anti-interference ability of the terminals can be improved by appropriately increasing the
reference value of P30.08. The more times the terminal filters, the longer the delay.
