Chapter V Basic Operation Instructions
5.1 Start operation mode
The HAV-SP series drive's start operation control includes three different ways as follows:
1. Start when the drive gives a run command normally;
2. Start after the automatic fault reset of the drive;
3. Start under the terminal two-wire start protection (the drive starts automatically when the
drive is powered on, the fault is cleared or the command channel is switched to the terminal
two-wire mode, which is only valid to terminal two-wire control).
The three different start-stop control statuses are described in the following.
5.1.1 Logic block diagram of start when the drive gives a run command normally
The HAV-SP series drive’s run command input has three channels namely keypad, terminal
and communication, and can be switched freely by input terminal and function code settings.
5.1. 2 Logic block diagram of start after the automatic fault reset of the drive
The automatic reset function can automatically reset the running faults according to the set
times and intervals. When the number of automatic resets is set to 0, it indicates that automatic reset
is prohibited and fault protection is performed immediately. Within 2 minutes after the drive
operates, if there is no fault, it will automatically clear the number of resets, and accumulate the
number of resets from the beginning.
The drive module protection (E010) and external equipment failure (E015) have no automatic
reset function. After the automatic reset is completed, it will automatically start and run at the speed
tracking.
For safety's sake, use this function with caution, otherwise, it may cause personal injuries
and property losses.
