The start command for a direction of rotation can be set by way of the
terminals of the inverter module. The start commands determine the
direction.
Attention: If the reference value (BUS, SIO, +/- 10 V, etc.) has a nega-
tive preceding sign, the fact is indicated on startup by an
inverted response, i.e. the motor shaft rotates anti-clockwise
in response to a clockwise start.
KEYPAD KP200
In the CONTROL menu the KEYPAD takes over complete control over the
inverter. It attunes the control location selector and the reference
channel 1 to itself. The second reference channel is shut off.
By way of the K
EYPAD control of the inverter can be seized and a refe-
rence value with preceding sign can be set to determine the direction of
rotation.
Parameters for setting and adapting the K
EYPAD are located in subject
area _36KP.
For more information on the K
EYPAD refer to the separate documentation,
“User Manual D
RIVEMANAGER and KEYPAD”.
STL STR Explanation
00
STOP, Motor is uncontrolled if stop ramp and DC braking are off.
Otherwise the motor decelerates with the programmed stop ramp or
the preset braking current down to 0 Hz and is then brought to a
standstill with the preset holding current for a variable holding time.
1 0 START anti-clockwise, Acceleration with ACCRx or DECRx
0 1 START clockwise, Acceleration with ACCRx or DECRx
11
BRAKING with DECRx or TDCRx. As soon as the motor reaches 0 Hz
it is brought to a standstill with the preset holding current if the DC
holding function is activated. Otherwise the motor is uncontrolled at
standstill.
The braking process can be interrupted by applying only one start
contact; the motor then accelerates again.
Reverse direction of rotation, overlap time (STL and STR = 1)
