Toshiba G7 manual Emergency Off DC Injection Application Time, Output Phase Loss Detection

F604 F608

Emergency Off DC Injection Application Time

Program ⇒ Protection Parameters ⇒ Emergency Off Settings

When DC Injection is used as a function of receiving an Emergency Off command (F603), this parameter determines the time that the DC Injection braking is applied to the motor.

Direct Access Number — F604

Parameter Type — Numerical

Factory Default — 0.10

Changeable During Run — Yes

Minimum — 0.00

Maximum — 10.00

Units — Seconds

output signal (U, V, or W) of the ASD. If either line is missing, inactive, or not
of the specified level, the ASD incurs a trip.

motor operation. During very low-speed operation the cooling efficiency of the
motor decreases. Lowering the start frequency aides in minimizing the	Minimum — 0.00

than 150%.
Inrush Current Suppression	Direct Access Number —	F608
Program ⇒ Protection Parameters ⇒ Soft Start	Parameter Type — Numerical
	Factory Default — 0.30

The startup inrush current may be suppressed for up to 2.5 seconds. This

parameter determines the length of the inrush current suppression.

Changeable During Run — No

Minimum — 0.30

Maximum — 2.50

Units — Seconds

Interlock with ST

Program ⇒ Protection Parameters ⇒ Soft Start

This parameter Enables/Disables the ST-to-CCconnection dependency on the successful completion of a Soft Start. If enabled, the ST-to-CCconnection will happen only after a successful Soft Start.

Direct Access Number — F609

Parameter Type — Check Box

Factory Default — Disabled

Changeable During Run — No
