Title P# Parameter Description
Parameter P0 Dummy Parameter Map unused bits, parameters etc.
P1 Station Number Unused
P2 Country Determines the language used by the display. 44=English.
P3 Software Type Manufacturers product code for the Soft-Start software.
P4 Software Version Version of the software.
Password P5 Password Value Allows you to set and enter a password.
Advanced P6 Firing Mode 0= Normal motor (outside delta or star)
1= Delta (inside delta, no optimization)
2= Closed loop phase control
3= Open loop phase control
Basic P7 Protection Mode Determines the fault protection method.
0= Input phase loss detection only.
64= Full protection with full volts after top of ramp.
128= Full protection during start then bypass (no protection)
192= Full protection + Optimization
Parameters P8 Status 1 Definition (Preset Value, all = 0)
Bit0= Stopped (1=Start/stop signal inactive, SCR's Off, Main contactor open).
Bit1= Starting (1= Starter is in Start Ramp).
Bit2= Current Limit (1=Motor current has reached limit and is being held).
Bit3= Top of Ramp (Full volts) (1=start ramp and current limit is complete).
Bit4= Dwell (1=the time at the end of the start ramp when the motor is
held at full volts before optimizing to stabilize the load).
Bit5= Full Conduction- (1= thyristors in continuous conduction).
Bit6= Energy Saving (1=Motor pf is monitored and volts are adjusted to optimum)
Bit7= Stopping (1=the stop ramp is active).
P9 Status 2 Definition (Preset Value, all = 0)
Bit0= Alarm (1=fault is detected and a trip has occurred)
Bit1= Overload Integrating (1=overcurrent is detected and is integrating)
Bit2= Stall (1=a stall condition is detected, motor speed decreasing).
Bit3= Forced Override (1= Optimizing not available even if selected because
motor current>80%FLA).
Bit4= Noise (1=Noise on AC input power mains is detected).
Bit5= Inhibit Start (1=Start is inhibited for a period to maintain duty cycle).
Bit6= DC I/P level reached (1= DC > P48).
Bit7= 4-20mA I/P level reached (1= 4-20mA > P46).
P10 Status 3 Definition (Preset Value, all = 0)
Bit0= K1 (1= K1 Active).
Bit1= K2 (1= K2 Active).
Bit2= K3 (1= K3 Active).
Bit3= K4 (1= K4 Active).
Bit4= Starter I/P 1 (1= Control Input1 is high).
Bit5= Starter I/P 2 (1= Control Input2 is high).
Bit6= Starter I/P 3 (1= Control Input3 is high).
Bit7= Red LED status (unused)
Basic P11 Start Pedestal Sets the voltage level for the Start of Voltage Ramp". Must be sufficient to allow
motor to generate a breakaway torque.
P12 Start Time Sets the time allowed for motor voltage to equal line voltage.
Advanced P13 Kick Pedestal Sets the voltage level at the start of the kickstart operation.
P14 Kick Time Sets the number of cycles that the P13 voltage is applied. Note that for
60 Hz, 40 cycles = 667ms. For 50 Hz, 40 cycles = 800ms.
P15 Dwell Time Sets the dwell time allowed after top of ramp is reached.
Basic P16 Stop Pedestal Sets the drop in motor voltage for the Stop Voltage Ramp" operation.
P17 Stop Time Sets the ramp down time for motor stopping.
Auto Features P18 Auto Config Auto configuration flags to use with the first parameter set.
Definition (Preset Value)
Bit0= Unused
Bit1= Auto 3MC (1, Auto remove low volt. ramp for high start pedestal).
Bit2= Auto Bypass (1, Enable Automatic Bypass Contactor detection).
Bit3= Auto Jog (0, Disable auto jog detect. If 1, a stop request within .5 sec
of a start request is forced to 0 stop time).
Bit4= Auto Endstop (0, Do not detect stalled motor at softstop).
Bit5= Auto Stop (0, Do not detect variations in pf during stop smooth stall).
Bit6= Auto Endstart (0, Do not detect full speed at start and adjust start ramp).
Bit7= Auto Pedestal (0, Do not detect rotation at start and adjust pedestal).
Advanced P19 Optimise Rate Sets the optimizing response rate. This parameter helps to stabilize small slip speed
motors with low inertia loads. (4=fastest optimizing rate).
