Operating conditions / Overload condition
Operating conditions:
Command
Operation
Drive response
STR or STL = “1“
Start
Inverter is ready for operation, drive is not running.
STR or STL = ”1”
and FSINA
≥
0.1 V
(or fixed frequency
selection)
Start +setpoint
Drive accelerates with ramp 32 RACC1 or 32 RACC2 in
selected direction of rotation.
Transition “0“ and ”1“ on
STR and STL
Reversal
Drive decelerates with ramp 33 RDEC1 or 35 RDEC2,
reverses and accelerates with ramp 32 RACC1 or 34 RACC2.
STR and STL = “1“
Important: not fail-safe!
Deceleration with
deceleration ramp
Drive decelerates with ramp 33 RDEC1 or 35 RDEC2.
STR and STL = “0“
Output voltage = 0
36 STOP = 0
→
motor uncontrolled, coasts to rest.
Stop with stop ramp
36 STOP > 0
→
motor decelerates with stop ramp 36 STOP.
Power down (K11)
EMERGENCY STOP
After power down wait for minimum 30s before you power
the inverter up again.
Overload condition:
An overcurrent of 150% I
N
for max. 60 seconds is permissible. If the thermal loading is too high the
Ixt monitoring will shut down the unit and generate a fault message (

Sec. 5.3).
