Parameter Index 4-1

MN850

Basic

Starting

Keypad – Allows motor starting and stopping by pressing Start/Stop key on keypad.

Remote – Allows motor starting and stopping by applying or removing 115VAC at

terminals S0 and S1 of the control board.

Start Pedestal

Start Pedestal Voltage – end of stop smoothing and beginning of low voltage ramp to

zero volts (if low voltage ramp is active).

Start Time

Number of seconds after the 3 cycle power–up to full motor voltage.

Stop Pedestal

Stop Pedestal Voltage is the percentage of line voltage applied to the motor after a stop

command.

Stop Time

Time in seconds after a stop command to ramp down the motor voltage (Stop Time 1 or

2). Stop Time 1 with low voltage ramp active. Stop Time 2 with no low voltage ramp.

Current Limit

Percentage of running current (P24 and P25).  Adjustable from 100 – 800%.

Power on
Parameter

Resets all parameter values to the values at the most recent power up.  Display blinks

twice to confirm reset is complete.

Protection

Full – provides shorted SCR protection during start and run, single phase protection

during start, optimizing not selected.

Full + Optimise – provides shorted SCR protection during start and run, single phase

protection during start, optimizing is selected.

Start + Bypass – provides shorted SCR protection during start, single phase protection

during start, optimizing not selected and no single phase protection during run.
This mode must be used with top of ramp bypass contactor.

Phase Loss only – shorted SCR protection during start and run is disabled, single phase

protection during start, optimizing not selected.
This mode is recommended when input power noise frequently causes nuisance trips.

Applications
