Actual values are 16-bit words containing sign bit and a 15-bit integer. A negative value is given as two’s complement of the corresponding positive value. Actual Value 1 Holding Register: 40005 Actual output frequency. Scaling: 5000 50 Hz. Actual Value 2 Holding Register: 40006 Actual output current. Scaling: 10 1 A. 28 Figure 12 The state machine for evaluation of start and stop signals.

These status words are located in place of parameter group 3 (Modbus holding registers 40301- 40309). These registers also contain copies of the Command Word (40001) and Status Word (40004). Registers 40301-40309 are generally read-only type; however, alarm words can be reset by writing zeros into the register. Table 10 lists the fault and alarm words. Table 10 Fault and alarm status words. No Name Description 40301 MAIN COMMAND WORD Read-only copy of the Command Word (40001). See page 24. 40302 MAIN STATUS WORD Read-only copy of the Status Word (40004). See page 26. 40305 FAULT WORD 1 Fault information. When a fault is active corresponding bit is set. Bit descriptions are given in Table 11. 40306 FAULT WORD 2 Fault information. Bits 0 - 7 of this register may be set if there is a hardware error in ACS 140 (fault codes 18 - 22). 40308 ALARM WORD 1 Alarm information. When an alarm is active corresponding bit is set. Bits remain set until whole alarm word is reset by writing 0 to it. See Table 12. 30 Table 11 FAULT WORD 1 bit descriptions. Table 12 ALARM WORD 1 bit descriptions.
