Type Hex Addr Dec Addr
P3.41 Digital Input Response Time
♦R/W 0329 40810
Range/Units Default
0~30�000 sec
0�005
This parameter sets the response time of the digital input terminals FWD, REV, and DI1~DI8.
NOTE: The response time of DI6 will not be affected by P3.41 when DI6=23. Use P3.40 for response
time when DI6=23.
This setting is for digital input terminal signal delay and confirmation. The delay time is
confirmation time to prevent some uncertain interference that would cause error in the input of
the digital terminals. Under this condition, increasing P3.41 would decrease the likelihood of false
triggers. Adjusting this response time effectively acts as a debounced input for some applications.
Use caution when adjusting this Response Time > default. If using Terminals for RUN/
STOP or for INC/DEC speed commands, the inputs will respond with the delay set in P3.41
(delay in responding to an input coming ON and going OFF). For most applications, keep
this response time as low as possible to reduce unintended consequences.

P3.42 Multi-Function Input Contact Selection (0=N.O. / 1=N.C.)
R/W 032A 40811
Range/Units (Format: 16-bit unsigned) Default
0~65535
0
The setting of this parameter is in hexadecimal (0 to FFFFh).
This parameter sets the normally open or normally closed default state for individual digital
inputs, and it won’t be affected by the SINK/SOURCE status.
User can also change normally closed or normally open status through communication with the
GS4 drive.
Changing the NO/NC status from the keypad or from a communications link will not cause
functions associated to those inputs to activate.
Example: You cannot cause the drive to run by changing the NO/NC configuration.
Bit0 is for FWD terminal, bit1 is for REV terminal and bit2 to bit15 is for DI1 to DI15.

P3.43 Multi-Function Output Contact Selection (0=N.O. / 1=N.C.)
♦R/W 032B 40812
Range/Units Default
0~65535
0
The setting of this parameter is in hexadecimal (0 to FFFFh).
This parameter sets the normally open or normally closed default state for individual digital
outputs. If a bit is 1, the corresponding output acts in the opposite way.
Example: If bit0 =1 and P3.17=1, relay output 1 (normally-open contact) is open when the drive is
running and is closed when the drive is stopped.

*NOTE: Outputs R1 and R2 are SPDT relays with both a normally open and a normally closed output.
Be aware of which contact you are wired to in order to correctly anticipate the output state.
