If REGISTER is selected, the reference is from OCL REF REGISTER (P.801).
The I/O Expansion kit must be installed to use ANALOG IN 1 (terminals 50 and 51 on
the I/O expansion board), ANALOG IN 2 (terminals 52 and 53), or FREQUENCY IN
(terminals 39, 40, and 41).
A communication kit must be installed to select the communication registers
(
NETW IN REG 1, 2, or 3). Note that the network input registers are updated only
when Control Source (P.000) is set to NETWORK and the network is active.
OCL REF RAMP TIME (P.802)
The ramp time for the
outer control loop
reference. Parameter Range: 0.0 to 300.0 seconds
Default Setting: 10.0 seconds
Parameter Type: Tunable
OIM Menu Path(s): Outer Control Loop ( OCL ) - OCL Tuning
Sets the minimum amount of time for the OCL S-curve block output to change from 0
to full scale and vice versa. If set to 0.0, the S-curve block is bypassed.
Important: If the S-curve block is bypassed, rapid speed change can result.
