18 GX9 ASD Quick Start Guide
RR
— The default function assigned to this terminal is Frequency Mode 1 . The RR terminal accepts
an analog 0 – 10 VDC input signal that is used to control the function assigned to this terminal. This
input terminal may be programmed to control the speed or torque of the motor via an amplitude setting
or regulate by setting a limit. The gain and bias of this terminal may be adjusted for application-specific
suitability (see
F210 – F215 ).
RX
— The default function assigned to this terminal is Torque Command . The RX terminal accepts an
analog ±10 VDC input signal that is used to control the function assigned to this terminal. This input
terminal may be programmed to control the speed or torque of the motor via an amplitude setting or
regulate by setting a limit. The gain and bias of this terminal may be adjusted for application-specific
suitability (see
F216 – F221 ).
II
— The II terminal is an isolated current input that is used to control the speed or torque of the
motor. Return at II (-). Select VI/II at F004 for speed control or select VI/II at F420 for torque
control. The II terminal receives a 0 – 20 mA input signal that controls the output 0.0 – Maximum
Frequency output or the -250% – 250% torque output of the ASD. Terminal scaling is accomplished
via F201 – F206 . The gain and bias of this terminal may be adjusted for application-specific
suitability (see F470 and F471 ).
VI — The VI terminal is an isolated voltage input that is used to control the speed or torque of the
motor. Select VI/II at F004 for speed control or select VI/II at F420 for torque control. The VI
terminal receives a 0 – 10 VDC input signal that controls the output 0.0 – Maximum Frequency
output or the -250% – 250% torque output of the ASD. Terminal scaling is accomplished via F201 –
F206 . The gain and bias of this terminal may be adjusted for application-specific suitability (see F470
and F471 ).
Note: The VI terminal or the II terminal may be used to control the speed or torque of the
motor. Selecting VI/II at parameter F004 enables both terminals for use, but both
cannot be used simultaneously. The user connects the proper input (current or
voltage) to the appropriate terminal to be used for control.
P24 — +24 VDC at 200 mA power supply for customer use.
PP
— The function of output PP is to provide a 10 VDC/10 mADC (max.) output that may be divided
using a potentiometer. The tapped voltage is applied to the RR input to provide manual control of the
RR programmed function.
OUT1
— The default function assigned to this terminal is External Device 1 . The function as External
Device 1 is to activate/deactivate an auxiliary motor once the Virtual Linear Pump level has remained
above the Maximum threshold setting or below the Minimum threshold setting for the time setting of
F931 . The OUT1 terminal is rated at 2 A/120 VAC and 2 A/30 VDC and may be set to any of the
functions listed in the GX9 ASD Installation & Operation Manual (see F130 ).
OUT2
— The default function assigned to this terminal is External Device 2 . The function as External
Device 2 is to activate/deactivate an auxiliary motor once the control level of the Virtual Linear Pump
settings has remained above the Maximum threshold or below the Minimum threshold settings for the
time setting of F931 . The OUT2 terminal is rated at 2 A/120 VAC and 2 A/30 VDC and may be set to
any of the functions listed in the GX9 ASD Installation & Operation Manual (see F131 ).
FP
— The default function of this output terminal is to output a series of pulses at a rate that is a
function of the ASD output frequency (50 mA max. at 1.0 kHz to 43.3 kHz). As the output frequency of
the ASD goes up, so does the
FP output pulse rate. This terminal may be programmed to provide an
output pulse rate that is proportional to the magnitude of the user-selected item listed in the GX9 ASD
Installation & Operation Manual . For further information on this terminal, see parameter F676 .
