Range/Units (Format: 16-bit unsigned)
0~50
(see P3�03~P3�16 Input Function Settings table below)
These parameters set the functions of the Multi-Function Input terminals.
• See Appendix C for Digital Input worksheet ( page
• Terminals for parameters P3�11 to P3�16 are located on the optional extention cards, if installed�
If there is no expansion card installed, these parameters remain virtual terminals� For example,
after installing the multiple function expansion card "GS4-06CDD," parameter P3�11 to P3�14 are
defined as corresponding parameters for terminals DI10 to DI13, but parameters P3�15 to P3�16
are still virtual terminals�
• When terminals are defined as virtual, you need a digital keypad such as GS4-KPD or a
communication mode to modify status of bits 8~15 (0=ON, 1=OFF) at Parameter P3�42�
• If an MFI will not take a setting, then most likely that setting is already assigned to a different
input� MFI inputs also cannot be changed when the drive is running�
• When an external input is used in the GS4 PLC and the PLC is in Run or Stop mode, the PLC then
owns that input and any Multi-Function Input setting assigned via P3�03~P3�16 is void� To read
the status of an input into the PLC while maintaining the MFI setting, use the RPR command on
the DI Status Register (P3�46)� The ownership of the I/O can be returned to the drive by disabling
the PLC either through the keypad or digital inputs when they are assigned values 36 and 37�

Function Description
Setting a Multi-Function Input to 0 will disable that input� The purpose of this
function is to provide isolation for unused Multi-Function Input Terminals�
Any unused terminals should be programmed to 0 to make sure they have
no effect on drive operation.
15 speeds can be commanded through the digital status of the 4 terminals; total
of 16 speeds if the master speed is included� (Refer to parameter group P5 for
settings�)
When settings 1, 2, & 3 are selected and registers P7�06~P7�12 are populated,
the Multi-Function Inputs refer to PID Multi-Setpoints� The SPs are determined
by P7�06~P7�12�
1) In order to use the Multi-PID SPs, P7.06~P7.12 must be set, and P7.00≠0.
2) When all PID Multi-Setpoint inputs are off, the GS4 drive reverts to the PID
Setpoint Source (P7�02)�
