Emergency Off Via External Signal; Emergency Off From The Operation Panel - Toshiba TOSVERT VF-AS3 Instruction Manual

Use this parameter when you want to set deceleration time for normal operation and emergency off
in different time.
4: Trip after Quick deceleration stop
After quick deceleration is performed, a trip occurs after stop.
In quick deceleration stop, the motor can decelerate more quickly than normal deceleration by
increasing the voltage to the motor (over-excitation control) to increase the energy consumed by the
motor when the voltage reaches the overvoltage limit operation level during deceleration.
5: Trip after Dynamic quick deceleration stop
A trip occurs after Dynamic quick deceleration stop.
In Dynamic quick deceleration, the motor may be decelerated more quickly than quick deceleration
control by increasing the voltage to the motor (over-excitation control) to increase the energy
consumed by the motor as soon as the motor starts decelerating.

■ How to use

1) Emergency off via external signal

4
Emergency off can be performed via a signal to a terminal. Assign "20: Emergency off" to the
input terminal. Select how to stop the operation in <F603>.
6
Emergency off from the terminals is always given priority even during panel run.

2) Emergency off from the operation panel

Emergency off can be performed on the operation panel when panel run is not performed.
To perform emergency off, press the [STOP] key on the operation panel twice.
For details on the operation, refer to [3. 2. 3].
9
The inverter cannot be reset the trip while the emergency off signal is being input to the input
terminal. Reset a trip after releasing the signal.
