This analog output varies from 0 to full scale and is referenced to COM terminal. It
may be programmed via parameter 71-METER to read output frequency, output
voltage, output current, output load in percent of inverter capacity and output motor
torque. The maximum full scale adjustment is calibrated by parameter 70-MCAL and
can be adjusted while the inverter is running. Maximum full scale adjustment is from
approximately 0-16.5 VDC. The output is rated at 5 mA. If proper wiring practices are
followed, no noise should be detectable on meter output. However, in some
applications noise can be observed. In this case, a 10µF capacitor can be inserted at
the terminal strip between MET and COM to minimize this effect.
Circuit common, isolated.

load referenced to COM. The current input
signal is calibrated by parameters 31-FMIN and 32-FMAX. FMIN sets the frequency 4
mA should generate, and FMAX sets the frequency 20 mA should produce. Operation
can be inverted, 20 mA = min. frequency, and 0 mA = max. frequency. (See
24-FSEL.)
Speed Reference input, 0 to 10 VDC or 0 to 2 VDC, selectable by jumper (J11). It will
also accept pulse train inputs: 0 to 1 kHz or 0 to 10 kHz, (6-10 V peak min.) and the
6FS output from another control. Operation can be inverted, 10 VDC = min.
frequency, and 0 V = max. frequency. (See 24-FSEL.)
This terminal is a +10 VDC power supply with 10 mA capacity and may be used as
the Torque Limit Reference supply or the reference for VIN, in which case the drive
can be programmed to shut down if the common line to the remote speed
potentiometer opens. (See 24-FSEL.)
Torque Limit input terminal. It will accept 0 to 10 VDC. 10 VDC equals 150% output
torque. Defaults to +10 VDC with no input connected.
Forward Direction Selection terminal. May be connected for two-wire maintained or
three-wire momentary operation.
Reverse Direction Selection terminal. May be connected for two-wire maintained or
three-wire momentary operation.
Reference Voltage for Digital inputs FWD, REV, R/J (Run/Jog), PS1, PS2, PS3, MOL
and ART, rated 200 mA. Overloading this terminal will result in fault F04. May be
used to power relays tied to open collector outputs ST1, ST2, and ST3.
Run/Jog Selector. When this terminal is connected to +24, momentarily connecting
either FWD or REV to +24 results in a latched run mode (3-wire operation).
Preset Speed #1 input • Preset Speed #2 input • Preset Speed #3 input
Eight preset speeds are attainable; one from the main speed setter, six programmed
speeds, and FMAX. Preset speeds can be programmed from 0 to 400 Hz, but FMAX
sets the actual operating range. (1 is closed to +24, 0 is open.) All may be obtained
from the following switching matrix:

Alternate Ramp Time Selector. Separate acceleration and deceleration ramps can be
selected by connecting this terminal to +24. These ramps are programmed by
parameters 41, 44 and 45. See parameter 21-MODE for more information on when
this function is active.
