RUN ro/rw
P-05 133 ✓ rw Stop Function 1
0 Ramp, deceleration = dynamic braking
Deceleration time with the value set under P-04 (dec1).
If the energy that is fed back by the motor during dynamic braking is too
high, the deceleration time must be increased.
In devices with an internal braking transistor, the excess energy can be
dissipated with an external braking resistance (optional)
(￫ Section 6.4.2, „Regenerative braking“, page 116).
1 Free coasting
After the start enable (FWD/REV) is switched off or the STOP button is
pressed (P-12 and P-15), the motor will coast uncontrolled.
2 Ramp, quick stop = dynamic braking
Deceleration time 2 with the value set under P-24 (dec2)
If the energy that is fed back by the motor during dynamic braking is too
high, the deceleration time must be increased.
In devices with an internal braking transistor, the excess energy can be
dissipated with an external braking resistance (optional)
P-18
146 ✓ rw K1 signal (Relay Output 1) 0
Used to select the function assigned to the relay output.
The relay has two output terminals: Logic 1 indicates that the relay is
active: This is why terminals 10 and 11 are connected to each other.
Output terminals; logic 1 indicates that the relay is active.
0 RUN, enable (FWD, REV)
1 READY, variable frequency drive ready for operation
2 Output frequency = frequency reference value
3 Error message (variable frequency drive not ready)
4 Output frequency ≧ limit value (P-19)
5 Output current ≧ limit value (P-19)
6 Output frequency < limit value (P-19)
7 Output current < limit value (P-19)
P-19
147 ✓ rw K1-Limit value (relay) 100.0
P-02 - 200.0 %
The adjustable limit value that is being used in connection with
settings 4 to 7 of P-18 and P-25
