There are two external interrupt input modes - normally on contact and normally off
contact. As shown in Figure 6-24, DI4 is a normally on contact input, and DI5 is a normally
off contact input.
Note: Different from functions 6 ~ 7, the external interrupt will not cause any
alarm output of the drive, after the interrupt signal is released, the drive restores operation.
19: Stop DC braking input instruction
The control terminal implements DC braking to the motor during stop, to realize
emergency stop and precise positioning of the motor. The braking start frequency, braking
wait time and braking current are defined in F2.09 ~ F2.11, and the braking time is the
larger of the time defined in F2.12 and the effective duration of the control terminal.
20: Closed-loop failure
Used to realize flexible switching with low-level operation mode in the closed-loop
operation mode (see introduction in 4.1.4).
Note: When closed-loop operation (F8.00=1) is valid, you can realize the switching
between closed-loop and low-level operation modes. When switched to low-level operation
mode, the start-stop control, direction, acceleration and deceleration time shall observe the
settings of corresponding operation mode.
21: PLC failure
Used to realize flexible switching with low-level operation mode in the PLC operation
mode.
Note: When PLC operation (F9.00 unit digit≠0) is valid, you can realize the switching
between PLC and low-level operation modes.
When switched to low-level operation mode, the start-stop control, direction,
acceleration and deceleration time shall observe the settings of corresponding operation
mode.
22~24: Frequency given channel selection 1~3
Through the ON/OFF combination of frequency given channel selection terminals 1, 2
and 3, the switching of frequency given channel in Table 6-8 can be realized. The
relationship between terminal switching and function code F1.02 setting is later effective.
