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 2
nd
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 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 (P-12=3 or 4).
4.7.2
Speed Reference Format (Standard resolution)
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.
4.7.3
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.
4.7.4
High Resolution Speed Reference
This register allows the user to set the speed reference value in the internal format, e.g. 3000 = 50.0Hz. This allows control resolution to 1 RPM
with a 2 pole motor. The maximum allowed 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.
