Block Title | Parameter | Description |
|
|
|
Advanced | Contactor Delay | A delay is required when an input contactor is energized by the |
|
| 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, |
|
| 1 – Induction motor (Delta), |
|
| 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 Menu
Block Title | Parameter | Description |
|
|
|
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). |
