H7 ASD Operation Manual 49
Frequency Mode #1
Program
⇒
Fundamental Parameters
⇒
Standard Mode Set
Frequency Mode #1 determines the source of the frequency command or the
torque command (when operating in the torque control mode) for the ASD.
If the Use EOI or Use LED Keypad Option is selected, the Local/Remote
key is enabled to select either the EOI, LED Keypad (local), or the
Control Terminal Strip (remote) as the command source.
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 RS232/485
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 5 on pg. 50.
Note: To read voltage at this terminal a 100 – 500Ω resistor is required and it
must be connected from FM (+) to FM (-). The voltage is read across the
100 – 500Ω 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
Parameter Type — Numerical
Factory Default — 512
Changeable During Run — Ye s
Minimum — 0
Maximum — 1280
