106 W7 ASD Installation and Operation Manual
RES Terminal
Program Terminal Settings Input Terminals RES
This parameter selects the functionality of the RES discrete input terminal.
In addition, the input terminal must be specified as Normally Open or
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.
Parameter Type — Selection List
Factory Default — Reset
Changeable During Run — No

RES Terminal Delay
This parameter delays the response of the ASD to any change in the RES
terminal input by the programmed value (see waveforms at
F Terminal Delay).
The delay may be increased to provide additional electrical noise immunity or
to prevent the ASD from responding to contact bounce or chatter.
Parameter Type — Numerical
Factory Default — 8.0
Changeable During Run — No
Minimum — 2.0
Maximum — 200.0
Units — mS
Ridethrough Mode
Program Protection Settings Ridethrough Mode
Enables/Disables the Ridethrough function.
In the event of a momentary power outage or a make/break at ST-to-CC, when
enabled, the Ridethrough function uses regenerative energy to maintain the
control circuitry settings.
Regenerated energy is not used to drive the motor.
Parameter Type — Selection List
Factory Default — Disabled
Changeable During Run — Yes
Ridethrough Time
Program Protection Settings Ridethrough Time
In the event of a momentary power outage, this parameter determines the length
of the Ridethrough time. During a Ridethrough, regenerative energy is used
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
parameter.
Note: The actual Ridethrough Time is load-dependent.
Parameter Type — Numerical
Factory Default — 2.00
Changeable During Run — Yes
Minimum — 0.00
Maximum — 320.0
Units — Seconds
