Operating Instructions
SIMOVERT MASTERDRIVES
Bit 16: Message "Restart-on-the-fly active" (H)
The restart-on-the-fly function is active, or the excitation time (P602) is
running.
♦
The drive converter is switched to a motor which is still rotating.
♦
Overcurrent is prevented as a result of the restart-on-the-fly
function.
♦
The excitation time (magnetization time) is active.
Bit 17: Message "Synchronism has been reached" (H)
Synchronism has been reached.
♦
Synchronism has been reached.
TSY (option) available and P100 (open-loop/closed-loop control type) =
2 (V/f characteristic for textile applications) or P100 = 1, 2, 3 at line
synchronism (P534 = 2).
Bit 18: Message "Overspeed" (L)
Alarm "Overspeed" (A033)
♦
The frequency actual value is either:
♦
greater than the maximum frequency for the clockwise rotating field
(P452) plus a hysteresis (P804 as %, referred to P452) or
♦
less than the maximum frequency for the counter-clockwise rotating
field (P453) plus a hysteresis (P804 as %, referred to P453).
♦
The bit is again set to an H signal as soon as the absolute value of
the frequency actual value is less than or equal to the absolute
value of the appropriate maximum frequency.
Bit 19: Message "External fault 1" (H)
"External fault 1"
♦
A "External fault 1" is present in control word, bit 15.
Output at the terminal strip (PEU, CUVC, TSY, SCI1/2, EB1, EB2) with L signal.
Bit 20: Message "External fault 2" (H)
"External fault 2"
♦
A "External fault 2" is present in control word bit 26.
Output at the terminal strip (PEU, CUVC, TSY, SCI1/2, EB1, EB2) with L signal.
