Bit 0:
Run/Stop command: Set to 1 to enable the drive. Set to 0 to stop the drive.
Bit 1:
Fast stop request. Set to 1 to enable drive to stop with 2nd deceleration ramp.
Bit 2:
Reset request. Set to 1 in order to reset the drive if drive is under trip condition.
User must clear this bit when drive is under normal condition to prevent un-expected reset.
Bit 3:
Coast stop request. Set to 1 to issue a coast stop command.
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
Start/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 (P-12=3
or 4).
9.2.2 Speed Reference Format
Speed reference value is transferred with one decimal place (200 = 20.0Hz). The maximum speed reference value is limited by P-01.
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.
9.2.3 Acceleration / Deceleration Ramp Time
Active only when P-12 = 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.
9.2.4 Drive status and error code Word
High byte gives drive error code. (Valid when the drive is tripped, see 0 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)
