All user configurable parameters are accessible as Holding Registers, and can be Read from or Written to using the appropriate Modbus
command. The Register number for each parameter P-04 to P-60 is defined as 128 + Parameter number, e.g. for parameter P-15, the register
number is 128 + 15 = 143. Internal scaling is used on some parameters, for further details please contact your Invertek Drives Sales Partner.

Range Explanation
0..3 16 Bit Word.
Bit 0: Low = Stop, High = Run Enable
Bit 1: Low = Decel Ramp 1 (P-04),
High = Decel Ramp 2 (P-24)
Bit 2: Low = No Function, High = Fault Reset
Bit 3: Low – No Function, High = Coast Stop Request
0..5000 Setpoint frequency x10, e.g. 100 = 10.0Hz
0..60000 Ramp time in seconds x 100, e.g. 250 = 2.5 seconds
Low Byte = Drive Error Code, see section 10. 1 . Fault
Code Messages
High Byte = Drive Status as follows:
0: Drive Stopped
1: Drive Running
2: Drive Tripped
0..480 Output Motor Current in Amps x10, e.g. 10 = 1.0 Amps
0.. 1 5 Indicates the status of the 4 digital inputs
Lowest Bit = 1 Input 1
0.. 1 000 Analog input % of full scale x10, e.g. 1000 = 100%
0.. 1 000 Analog input % of full scale x10, e.g. 1000 = 100%
0.. 1 000 Displays the setpoint frequency x10, e.g. 100 = 10.0Hz
0.. 1 000 DC Bus Voltage in Volts
0.. 1 00 Drive heatsink temperature in °C
