H-2 GV3000/SE AC Drive Software Reference, Version 6.06
If a Remote Meter Interface (RMI) board is installed, P.064 is used to select the OCL
reference as follows for FVC/SVC applications only:
• 0 = RMI analog input
• 1 to 8 = Preset speed 1 to 8 (P.031 to P.038), respectively
If no option board is installed, P.064 is used to select the OCL reference for FVC/SVC
applications only:
• 0 = Preset speed 8 (P.038)
• 1 to 8 = Preset speed 1 to 8 (P.031 to P.038), respectively
The OCL feedback is either the drive’s scaled terminal strip analog input (default) or
the speed loop PI output (user option). The feedback is fed through a lead/lag block
which can be configured as a lead/lag, lag/lead, or null (bypass) function.
If a network option board is installed in the drive, the OCL enable signal is controlled
by a bit in the drive control word.
If an RMI board is installed, the OCL enable signal is controlled by the RMI digital
input (configured for RMI PI regulator enable) or by the same internal signal used to
control the speed loop enable signal. (Refer to the r.030 parameter description in the
RMI instruction manual, D2-3341, for more information.)
If there is no option board installed, the OCL is enabled when the drive is running (that
is, the speed and torque controllers are active) and is disabled if the drive is stopped.
If the drive is running and the OCL enable signal is on (closed), the outer loop will
operate. If the enable signal is off (open) or the drive is not running, the outer loop is
held in reset.
