Title P# Parameter Description
Parameters
100 Flag1 O/P Destination Mask The bit mask for destination flag parameter.
Continued
101 Flag2 I/P Source Address Address of source flag parameter.
(Parameter 102 is the mask for P101.)
102 Flag2 I/P Source Mask The bit mask for source flag parameter.
103 Flag2 O/P Destination Address Address of destination flag parameter.
(Parameter 104 is the mask for P103.)
104 Flag2 O/P Destination Mask The bit mask for destination flag parameter.
105 Loop Input The parameter number used as the source for control loop setpoint.
106 Loop Feedback The parameter number used as the source for control loop feedback.
107 Error Gain Multiplier for the control loop error signal.
108 Error Divisor Divisor for the control loop error signal.
109 Max Slope The maximum allowed single error in open loop.
110 Guard Gap The minimum allowed firing delay in both open loop and phase
control modes. This allows for jitter and power factor of the load.
Parameters
111 User Parameter This parameter may be set by the user by the serial link.

112 Status 4 Definition (Preset Value, all = 0)
Bit0= The unit is using 60Hz parameters
Bit1= The phase rotation detected at start (RYB Sequence)
Bit2= Indicates current is greater than shearpin level
Bit3= Indicates current is less than under current level
Bit4= Thermistor is overtemperature or I/P's are open circuit
Bit5= Current limit has timed out
Bit6= Overload has passed trip level
Bit7= Heatsink temperature is greater than max allowed
113 Drive Type Unused
114 Baud Rate Unused
115 Selected App Value selected from application table. Not implemented on some
versions of software.
116 5MC Inhibit Time (restart not allowed) Number of minutes after stop that restart is not allowed. (Protects
SCR’s for large loads.)
117 Command Source Unused

120 Status 5 Definition (Preset Value)
Bit0= Thermal Switch 2 Over temp . Prevents re-start if set. (0, Off)
121 User Flags 4 Definition (Preset Value)
Bit0= Unused
Bit1= Allow for quicker comms response (0, Off)
Bit2= enable Soft stop smoothing for pumps (0, Off)
122 Soft–Start Smoothing Sets the amount of soft–start smoothing. This parameter helps
stabilize jitter caused by unstable loads.
