Serial Communications 79
For normal operation, Bit 3 has the highest priority, bit 0 has the lowest priority (bit
3>bit 1>bit 0). For example, if user set command as 0x0009, drive will do a coast stop
rather than run. For normal run/start, just set this register to 1.
Note that stat/stop (bit 0), fast stop (bit 1) and coast stop (bit 3) only works if P-31= 0
or 1. Otherwise, start/stop function is controlled by drive control terminals. Reset
function (bit 2) works all the time as long as drive is operated under Modbus control
mode (1103=3 or 4).
Register 2: Speed Reference
This register holds the speed reference value with one decimal place (200 = 20.0Hz).
The maximum speed reference value is
limited by 2008. Either register 2 or register 5 can be used for speed reference
control, however only one reference should be
used in any control system, otherwise unexpected behaviour can result.
Register 4: Acceleration / Deceleration Ramp Time
Active only when 1103 = 4, this register specifies the drive acceleration and
deceleration ramp time. The same value is applied
simultaneously to the acceleration and deceleration ramp times. The value has two
decimal places, e.g. 500 = 5.00 seconds.
Read Only Registers
Register 6: Drive status and error code
High byte gives drive error code. (Valid when the drive is tripped, see Appendix D –
Drive Fault Code and Information for further
details)
Low byte gives drive status information as follows :-
Bit 0: 0 =Drive Stopped, 1 = Drive Running
Bit 1: 0 = OK, 1 = Drive Tripped
Bit 5: 0 = OK, 1 = In Standby Mode
Bit 6: 0 = Not Ready, 1 = Drive Ready to Run (not tripped, hardware enabled and no
mains loss condition)
Parameter Registers and Scaling
All user adjustable parameters within the drive are accessible by Modbus, and can be
Read or Written to. For further information regarding the parameter functions and
specific settings, please refer to the User Guide.
