H2: Multi-Function Output - Omron V1000 User Manual

Setting 7C/7D: Short Circuit Braking (N.O./N.C.) (PM OLV only)
An input programmed for this function can be used to activate Short Circuit Braking in Open Loop Vector Control for PM
motors. By linking all three phases of a PM motor it creates a braking torque in a rotating motor and can be used to stop
a rotating motor or prevent a motor from coasting by external forces (like windmill effect in fan applications etc.).
Description
Normal operation
Short-Circuit Braking
Setting 7E: Forward Reverse Detection (V/f Control with Simple PG Feedback)
When a digital input is programmed for this function, the input determines the direction of the speed feedback signal for
V/f Control with PG feedback. If the input is open, the speed feedback signal is considered to be forward, if the input is
closed, it is considered to be in reverse.
Setting 7F: Bi-Directional PID Output Selection
If PID output to bi-directional output conversion is enabled in parameter d4-11, a digital input programmed for 7F can be
used to switch between normal output or bi-directional output.
If the digital input is open, the PID output builds the output frequency reference. If the input is closed, the PID output is
converted to bi-directional output frequency reference.
Setting 90 to 96: FBDs Digital Input 1 to 6
These settings are for digital inputs functions used by FBDs. Normally there is no need to change or apply these settings.
Setting 9F: FBDs Function Disable
This function is used to enable or disable a FBDs program in the drive. An input programmed for this function is effective
only if A1-07 = 2.

n H2-01 to H2-03: Terminal MA/MB/MC, P1/PC and P2/PC Function Selection
The drive has three multi-function output terminals. Set parameters H2-01 to H2-03 between 0 and 192 to assign functions
to these terminals. Default values are listed in the following table.
No.
H2-01 Terminal MA, MB and MC Function Selection (relay)
H2-02 Terminal P1 Function Selection (open-collector)
H2-03 Terminal P2 Function Selection (open-collector)
Note: If not using an input terminal or if using it in the through-mode, be sure to set that terminal to "F".
