Frequency Mode #1
The Frequency Mode #1 setting establishes the source of the frequency-control
input for the ASD. The Override feature may supersede the Frequency
Mode #1 setting (see
Command Mode and Frequency Mode Control on pg. 31
).
Note:
Only Bolded items from the Settings list below may be placed in
the Override mode. See the section titled
Command Mode and
Frequency Mode Control on pg. 31
for further information on the
Override feature.
Settings:
Use VI/II
Use RR
Use RX
Use Option Card RX2
Use LED Keypad Option
Use Binary/BCD Input
Use Common Serial (TTL)
Use RS232/RS485
Use Communication Card
Use Motorized Pot. Simulation
Use Pulse Input Option
Direct Access Number — F004
Parameter Type — Selection List
Factory Default — Use RR
Changeable During Run — No
FM Terminal Assignment
Program
⇒
Meter Terminal Adjustment Parameters
⇒
FM
This setting determines the output function of the FM analog output terminal.
The FM output terminal produces an output current that is proportional to the
magnitude of the function assigned to this terminal. The available assignments
for this output terminal are listed in
Table 7 on pg. 61
.
Note:
To read voltage at this terminal a 100 – 500
Ω
resistor is
required and it must be connected from FM (+) to FM (-). The
voltage is read across the 100 – 500
Ω
resistor.
Current may be read by connecting an ammeter from FM (+) to
FM (-).
The FM analog output has a maximum resolution of 1/1024. The FM Terminal
Adjustment (
F006
) must be used to calibrate the output signal for a proper
response. SW-2 may be switched to allow for the full-range output to be either
0 – 1 mA or 4 – 20 mA when providing an output current, or either 0 – 1 or 1 –
7.5 volts when providing an output voltage at this terminal.

FM Terminal Adjustment
Program
⇒
Meter Terminal Adjustment Parameters
⇒
FM
This function is used to calibrate the FM analog output terminal.
To calibrate the FM analog output, connect a meter (current or voltage) as
described at
F005
. With the drive running at a known frequency, adjust this
parameter (
F006
) until the running frequency produces the desired DC level
output at the FM terminal.
Direct Access Number — F006

Factory Default — 512
Changeable During Run — Yes
Minimum — 0
Maximum — 1280
