◆T1～T4: Preset Acc/Dec time separately. If more than one Acc/Dec time function
terminals are enabled, the lower terminal function selection will be prior.
◆TT1～TT2: Combinations of the two terminals to make Acc/Dec time 1～4, as shown
in Table 5-3-3.
◆If simultaneity defined T1~T7 and TT1~TT2, T1~T7 is prior.
37～40: External fault signal / External interrupt signal (normally open / normally close)
EH0 - External fault signal normally open / EH1 - External fault signal normally close:
External fault command. If the setting is 37-40, the fault signal of external equipment
can be input by the terminal. Once the ac drive receives the fault signal, it stops output
immediately, and displays last fault code. After the external fault signal is removed, the
ac drive needs to be reset before restarting. Tips: Ac drive can’t reset if external fault
signal isn’t released. EH0 and EH1 are not influenced by P3.00 (Terminal function
mode), Shown in Fig.5-3-6.
EI0 - External interrupt signal normally open / EI1 - External interrupt signal
normally close: During operating, the ac drive stops its output and runs at zero-speed
when it receives external interrupt signal. Once the signal is removed, the ac drive will
start and resume normal operation. Please refer to note of EH0 and EH1 above. As
shown in Fig. 5-3-6.
