Remote START/STOP Connections Possibilities

Terminal Connection Action

ST-CC F-CC R-CC

OFF ON/OFF ON/OFF The inverter is OFF. OFF will be displayed. If running

when ST-CC is broken the motor will coast to a stop.

ON OFF OFF The inverter is ON but not running.

ON ON OFF The inverter is ON and will run in a FORWARD direction if an

input signal is applied.

ON OFF ON The inverter is ON and will run in a REVERSE direction if an

input signal is applied.

ON ON ON Same as REVERSE connection above.

ON = dry contact closure, OFF = dry contact opening

Notes:

1) With ST-CC (ON), switching F-CC or R-CC (OFF) will cause the motor to decelerate to a stop.

2) If input power is turned off (with MCCB) while inverter is running, the motor will coast to a stop.

Avoid using the input power switch to start and stop the motor use for an emergency

stop oniy.

3) Acceleration and Deceleration rates are determined by the preset values of function [:ACC1],

[:ACC2] and [:DEC1], [:DEC2].

4) When switching from a forward run to a reverse run the motor will decelerate to a stop then

accelerate in the reverse direction.

10.3 Emergency Stop From a Remote Location

A SPST normally closed latch-in type of switch should be connected between ST-CC.

This switch can then be located in a remote location. When the switch is "toggled" to

latch open, the motor will coast to a stop.

CAUTION

Do not toggie this switch ON again untii the inverter is turned OFF (the

output frequency reads zero) and the motor ioad has stopped rotating.

10.4 Remote control Frequency Setting

The drive can be run at various frequencies by use of external analog voltage and current

control signals applied to terminals IV and RR. The keypad is not used for this operation

other than assignment of values and programming instructions. It may be desirable from

a security standpoint to disable the touchpad, when programming is completed, so that

customer parameters and programming cannot be changed or revised. Use function

[:RR.cc] item 2 on page 7-5 to set the terminals. When the IV input is selected, an

auto-mode is in effect so that voltage sensing terminal RR will override current

sensing terminal IV if a voltage is applied to terminal RR. See Terminal/Jumper

Connections for Input Reference Signals chart on page 5-6.
