Drive Function Code Access; Command And Monitor Data Registers - GE AF-300 P11 User Manual

12.5 Drive Function Code Access

All of the drive function codes are accessible through the RS485 serial interface. Drive function codes are mapped to
RTU holding registers. A drive function code RTU address is 2 bytes in length. The high byte corresponds to a code that
represents the drive parameter sort (F–M). The low byte corresponds to the drive parameter number within the sort (0 -
99).
Code Sort Name
0 F Basic function
1 E Terminal function
2 C Control function
3 P Motor 1 function
4 H High level function
For example, drive function code M11, output current, is addressed as RTU parameter number 080B hexadecimal or
2059 decimal.

12.6 Command and Monitor Data Registers

The command and monitor function codes are used to control the operation of the drive and monitor the status variables
through the serial interface. The command and monitor function codes are not accessible from the drive keypad
interface. Drive parameter H30 and digital input signal LE must be enabled to operate the drive from the Modbus
interface. If LE is not assigned to a digital input (X1-X9), the signal will default to ON.
Frequency Setting Registers
Address Code Name
1793 S01 Frequency command
1797 S05 Frequency command
Note:
1) If both S01 and S05 are set, the drive will ignore the setting of S05.
2) A data setting that exceeds the setting range is possible, but the actual action will be limited by the drive configura-
tion.
Operation command data Registers
Address Code Name
1798 S06 Operation command
1799 S07 Universal Do
1804 S12 Universal Ao
Note:
1) Since X1–X9 are configurable input commands, it is necessary to set the functions by E01–E09.
2) The alarm reset is executed, when RST signal changes from ON to OFF even if there are no alarms.
3) Universal Do is a function that utilizes the drive's digital outputs via communication.
Function data Registers
Address Code Name
1800 S08 Acceleration time F07
1801 S09 Deceleration time F08
1802 S10 Torque limit level 1
(driving) F40
1803 S11 Torque limit level 2
(braking) F41
Note:
1) The writing of data out of range is treated as out of range error.
2) Use a value of 7FFF to enter 999 for torque limit functions.
