be indicated by the digital input 16.
34: DC braking(at stop). During stop, if this signal is valid when the operating frequency is less than
F1-26 and F1-25=2, the DC braking is introduced until the braking time exceeds F1-28 and this signal is
canceled.
35: Process PID disabled. This signal invalidates the PID operation. Only when it is invalid and there is
no operation mode with a higher priority than PID, can the PID operation begin.
36: PID parameter 2. If this signal is valid when F7-11=0, the second set of PID
parameters(F7-08~F7-10) will be selected, otherwise the first set be selected(F7-05~F7-07).
37~39: 3-wire stop command, internal virtual FWD and REV terminals. Refer to F4-08.
40: Analog reference frequency hold. If this signal is valid when the reference frequency comes from
the analog input, the reference frequency will not change with the analog input, otherwise it will. This
function is quite useful in applications where the analog input is vulnerable to the electromagnetic disturbance.
Refer to the diagram below.

Analog reference frequency hold
41: Accel/decel disabled. When this signal is valid, the accel/decel process will stop, otherwise the
accel/decel process will resume.
42: Run command source switched to terminal/keypad. This signal, in conjuction with F0-02, can
switch the command source from one to another, as shown in the following table.
F0-02
0: Keypad
1: Terminal
2: Communication
43: Reference frequency switched to AI1. When this signal is valid, the frequency setting channel will
be forcibly switched to AI1, otherwise the frequency setting channel will be restored. If the priority is higher
than digital input 44, the frequency setting channel will be switched to arithmetic unit 1.
44: Reference frequency switched to arithmetic unit 1. When this signal is valid, the frequency setting
channel will be forcibly switched to arithmetic unit 1, otherwise the frequency setting channel will be restored.
If the priority is lower than digital input 43, the frequency setting channgel will be switched to AI1.
45: Speed/torque control select. This signal switches the control mode between torque control and speed
control. If it is valid, the control mode is speed control, otherwise the torque control.
46~48: Multi-PID select 1~3. The combination of multi-PID select 1, 2 and 3 determines which PID
reference is selected, as shown in the table below.
