Contactor Delay

A delay is required when an input contactor is energized by the soft–start “Run” relay.

 

 

This delay allows bouncing contactor armature to settle during the “Closed” position.

 

 

Value can be 20 to 800 milliseconds. Parameter 71.

 

 

 

 

Trip Sensitivity

A numerical value that sets the sensitivity level for all trips. A larger number provides

 

 

slower response to a trip. Value can be 1 to 15. Parameter 72.

 

 

 

 

Station Number

Reserved for future use.

 

 

 

 

Language

English (44) is preset. Value can be 1 to 255. Parameter 2.

 

 

 

 

Firing Mode

Sets the SCR firing mode to one of the following: (Value can be 0 to 3. Parameter 7.)

 

 

0 – Normal, 3 phase induction motor, Soft–Start conducting line current.

 

 

1 – Induction motor (Delta), Soft–Start conducting phase current.

 

 

2 – Closed loop phase control for electrical loads other than motors.

 

 

Current sensing is active but current protection is disabled.

 

 

3 – Open loop phase control for electrical loads other than motors.

 

 

Current sensing is disabled and current protection is disabled.

 

 

Note: Modes 2 and 3 are not suitable for motor loads and may damage motor and

 

 

control. These modes are suitable for electrical loads such as lighting or

 

 

resistive heaters.

 

 

 

 

Stop Smoothing

Adjustable voltage ramp for smooth deceleration. Motor current is monitored and stop

 

 

smoothing will continue until the Start Pedestal value is reached. Value can be 1 to

 

 

255. Parameter 122.

Auto Features

Settings

Display starting method, either Keypad or Remote. Also displays operating mode

 

 

(Optimizing or Full Voltage).

 

 

 

 

Auto Jog

If on, and Stop is commanded within 0.5 seconds of a start command the control will

 

 

change to jog mode. In jog mode, the decel ramp is changed to 0 seconds.

 

 

Repeatedly pushing the Start/Stop button will cause the motor to move slightly in the

 

 

same direction.

 

 

 

 

Auto Pedestal

If on, will automatically increase the voltage pedestal to start motor rotation.

 

 

 

 

Auto End Start

If on and motor reaches full speed during ramp up, the start ramp will be terminated and

 

 

full voltage will be applied to the motor.

 

 

 

 

Auto Stop

If on, automatically activates stop smoothing if required by the load during stop for

 

 

smooth deceleration of the load.

 

 

 

 

Auto End Stop

If on, detects a stalled or stopped motor and terminates ramp down (turns SCR’s off)

 

 

during stop.

 

 

 

 

Auto Bypass

If on, control detects the bypass contactor closing and automatically disables shorted

 

 

SCR detection (activates shorted SCR detection when contactor opens).

 

 

 

 

Auto 3MC

If on, reduces inrush current by allowing the motor voltage to build up from zero to the

 

 

set voltage pedestal over 2 to 3 cycles. On “Sticky” or “Traction” type loads, this

 

 

mode allows dynamic boost and stall sensing to start load.

 

 

 

 

Auto Off

Off – No effect.

 

 

On – changes the setting of all “Auto” parameters. If on, the parameter turns off etc.

 

 

 

 

Stop Smoothing

If on, allows motor deceleration smoothing (see Stop Smoothing Rate, Advanced menu).
