Title P# Parameter Description
Parameters
P20 Reference PF (Power Factor) The calculated power factor to optimize the control loop.
P21 Present PF (Power Factor) The present power factor of the motor (load).
P22 Delay Angle (SCR OFF time) The period (in degrees) that the thyristors are in the OFF state.
P23 Maximum Optimizing Delay Sets the maximum delay angle (max degrees that the thyristors are
OFF) used during the optimizing mode.
P24 Rated Current (High Byte –Hundreds) The current rating of the soft–start set by manufacturer.
P25 Rated Current (Low Byte – Units) The current rating of the soft–start set by manufacturer.
P26 Running Current Amps
The load current. (Always shown as phase current).
(RatedCurrent) x (7.96875)
32
P27 Peak Start Current (measured at last start) The maximum current used during the last start–up.
Advanced Current
P28 Low Current Level (undercurrent trip)
(scaling = 0.03125)
Sets the under current trip level. (The low current level flag is
updated even if the low current trip is disabled).
P29 Low Current Time (delay before trip) The number of cycles allowed for a low current level condition (P28)
to exist before tripping. For 60 Hz, 40 cycles = 667ms.
For 50 Hz, 40 cycles = 800ms.
P30 Current Limit Level (scaling = 0.03125)
(RatedCurrent) x (7.96875)
32
Sets the level that the start ramp is held. (The start ramp is only held
if the P30 value is reached. The current decreases as motor speed
increases allowing the ramp to continue).
P31 Current Limit Time (delay before trip) The time allowed for start current to equal P30 value before tripping.
Note that for 60 Hz, 40 cycles = 667ms.
For 50 Hz, 40 cycles = 800ms.
P32 Shearpin Level (overcurrent trip) Sets the over current trip level. Shearpin operation begins after
start–up is complete.
P33 Shearpin Time (delay before trip) The number of cycles allowed for an overcurrent condition before
tripping (only when shearpin flag P51, Bit3=1). For 60 Hz, 60 cycles
= 1second. For 50 Hz, 50 cycles = 1second.
P34 Overload Level (SCR protection) Sets the overload current level as a portion of FLA. (P34 is always
active but P30 is only active during motor starting.)
P35 Overload Delay (delay before trip) The time allowed for an overload condition before tripping. For 60
Hz, 60 cycles = 1second. For 50 Hz, 50 cycles = 1second.
Parameters
P36 % Overload (status only) The integration of the Current–Time product represented as a % of a
value that was preset by the manufacturer.
P37 Chassis Temp The heatsink temperature. When the temperature exceeds a
threshold value, P37 value will change from <20 to >200.
P38 Pot1 The value of RV1 on the control card. 255=fully CW setting for
5VDC input. (Not applicable for keypad operation).
P39 Pot2 The value of RV2 on the control card. 255=fully CW setting for
5VDC input. (Not applicable for keypad operation).
P40 Pot3 The value of RV3 on the control card. 255=fully CW setting for
5VDC input. (Not applicable for keypad operation).
P41 DC I/P 0–12V input for load monitoring or phase angle setpoint etc.
P42 Thermistor Monitors the Thermistor I/P (standard motor thermistor). The values
are not all that useful as thermistors act much like a switch.
P43 4–20mA I/P Monitors the 4 to 20mA input. Note this input is referenced to the
PCB 0V and so cannot be used with daisy chained sensors.
P44 TEMP Trip Level The value at which Parameter 37 causes a trip.
P45 4–20mA MAP Value is the Parameter to which the 4–20mA data is sent.
P46 4–20mA Set Level Value is the level at which the 4–20mA level bit will be set.
P47 DC Input Map Value is parameter to which the DC input data is sent.
P48 Set Level DC I/P Value is the level at which the DC–I/P level bit will be set.
P49 MAP DAC O/P 1 The value is the parameter that is the source for DAC 1 (0–10VDC).
P50 MAP DAC O/P 2 The value is the parameter that is the source for DAC 2 (0–10VDC).
