Toshiba W7 manual RES Terminal Delay, Ridethrough Mode, Ridethrough Time

RES Terminal							Ridethrough Time
RES Terminal
Program	⇒	Terminal Settings	⇒	Input Terminals	⇒	RES	Parameter Type — Selection List
							Factory Default — Reset
This parameter selects the functionality of the RES discrete input terminal.
In addition, the input terminal must be specified as Normally Open or							Changeable During Run — No
Normally Closed.
This parameter sets the programmable RES terminal to 1 of the 69 possible
functions that are listed in Table 6 on page 138.
RES Terminal Delay
Program	⇒	Terminal Settings		Terminal Delays		Input Terminal	Parameter Type — Numerical
Delays			⇒⇒
	RES Terminal Delay						Factory Default — 8.0
This parameter delays the response of the ASD to any change in the RES							Changeable During Run — No
terminal input by the programmed value (see waveforms at F Terminal Delay).
The delay may be increased to provide additional electrical noise immunity or							Minimum — 2.0
to prevent the ASD from responding to contact bounce or chatter.							Maximum — 200.0
							Units — mS
Ridethrough Mode
Program		Protection Settings		Ridethrough Mode			Parameter Type — Selection List
Enables/Disables the Ridethrough function.							Factory Default — Disabled
In the event of a momentary power outage or a make/break at ST-to-CC, when							Changeable During Run — Yes
enabled, the Ridethrough function uses regenerative energy to maintain the
control circuitry settings.
Regenerated energy is not used to drive the motor.
Ridethrough Time
Program	⇒	Protection Settings		Ridethrough Time			Parameter Type — Numerical
			⇒				Factory Default — 2.00
⇒
In the event of a momentary power outage, this parameter determines the length
of the Ridethrough time. During a Ridethrough, regenerative energy is used							Changeable During Run — Yes
to maintain the control circuitry settings; it is not used to drive the motor.
The Ridethrough will be maintained for the number of seconds set using this							Minimum — 0.00
							Maximum — 320.0
parameter.
Note: The⇒actual Ridethrough Time⇒is load-dependent.							Units — Seconds
