Frequency Setting
Common terminal for terminals 12, 13, Cl (Do not
Common Terminal connect to CM terminal or electrical noise immunity may be lost )
Frequency Setting
Voltage Input
When 0 to +10 Vdc (0 to 5V*) IS input, the maximum frequency is
reached at +lO Vdc (5V*) and is proportional to output frequency
down to 0 Vdc. Input impedance
IS
22K ohm. *200% gain setting
Frequency Setting Regulated +lO Vdc power supply for frequency setting potentiometer,
Voltage Output Term

OmA or less (13 to terminal 11.)
Frequency Setting
Current Input (+)
When the Input signal is +4 to +20mA dc, the maximum frequency is
reached at 20mA and IS proportional down to a minimum frequency
setting at 4mA. Input impedance is 250 ohm Must be isolated source
Control Circuit Common terminal for control input commands, and FMP pulse
Common Terminal output signal. (Do not connect to terminal 1

Forward Command
Input Terminal
Reverse Command
Input Terminal
Forward command via FWD-CM (closed). Reverse command via
REV-CM (closed). When FWD-CM
IS
closed and REV-CM IS closed
at the same time, the Drive will decelerate to stop.
Motor Coast-To-Stop
Input Terminal/Reset
Input
Motor will coast-to-stop with BX-CM (closed) (For use when
applying mechanical brake with Drive
in
operation.) Note. If
BX-CM is opened with FWD or REV closed, the Drive will start
operating
External thermal trip
command
CONTROL TERMINAL BOARD
After removal of fault condlbon, Faults are reset when a momentary
contact closure is made between the RST-CM terminals for more
than 0.1 seconds.
NOTE:
If there
IS
an mpuf to the FWD and/or REV terminals, the unit
will not RESET.
With THR-CM (open), OH trip
will
occur and the motor will
coast-to-stop.
NOTE:
With no external thermal relay or external braking resistor
thermostat, fhe THR-CM termmals must be closed or the Drwe
will not operate.
