INTERFACE / Commands
For starting, the drive always requires the Enable command, Start command and Fast
stop when enabled. The above different commands affect the drive rotation:
Enable This command unlocks power converter firing. It is made of a terminal wired
permissive that affects firing hardware directly. In addition, this can be
optionally ANDed with a boolean input "Digital enable" from an external
source (communication, application card).
Enable command can also be "gated" by the "En/Disable control function" as
described below.
Enable unsuicides the drive regulators and current can circulate.
See Diagram Block chapter , "Commands - Enable logic".
Start/Stop This command unlocks the reference to the regulation chain: Ramp, speed
regulator or torque regulator, depending on which is enabled.
When the command is asserted (0 to 1 transition) it is said that the drive is
being "started", when the command is negated (1 to 0 transition) it is said
that the drive is being stopped".
The Command select parameter defines the use of Enable drive and start/stop of the
drive. It may have different source:
• Terminal: Enable and Start and Stop commands are active from programmable
digital input terminals. Enable has a dedicated input, Start is programmed as
default as Term Str/Stp src (Start & Stop can also be separate commands from PB
inputs). If the command source is Digital or I O Keys, terminals are acting as
permissive inputs.
• Digital: The commands come as boolean input "Dig Str/Stp" from a communication
or application card. (Terminals are acting as level sensitive permissive inputs)
• [I] and [O] keys on the keyboard/display module. (Enable terminal are acting as
level sensitive permissive inputs)
Through "Terminal" and "Digital" can be select an "edge-sensitive" section, which is
meant for manual control from an operator, or automatic control from a PLC, and a "level-
sensitive" section, which is meant for wired control in an unmanned installation where
automatic restart after power fault is desired.
For unmanned installations requiring the drive to restart after a power fault without any
external sequencer logic, the edge sensitive section may be bypassed by setting
parameter Command select = "Terminal Level". See Diagram Block chapter , "Commands
- Start Stop logic".
NOTE! With Command select = "I O Keys", the [O] key on the keyboard/display module
(if present) can be used to stop the drive. In this case, to resume normal operation,
the [I] key must be pressed, alternatively power must be cycled in orded to clear
the sequencer. The keyboard/display module can be used as a monitor device with
the different selection of Command select parameter.
