1/0 Ramp-up starts.

The start of the ramp-up procedure is detected as

follows:

The speed setpoint changes,
and

the defined tolerance bandwidth (p2164) is

exited.

0

Ramp-function generator active

The ramp-up procedure is still active once the

speed setpoint has been changed.

0/1 Ramp-up ends.

The end of the ramp-up procedure is detected as

follows:

The speed setpoint is constant,
and

The actual speed value is within the tolerance

bandwidth and has reached the speed setpoint,
and

The waiting time (p2166) has elapsed.

1

Torque utilization < p2194

The current torque utilization is less than the set

torque utilization threshold (p2194),

or

Ramp-up is not yet complete.

Torque utilization < p2194

0

Torque utilization > p2194

The current torque utilization is greater than the

set torque utilization threshold (p2194).

BO: r2199.11

1

Application:

This message indicates that the motor is overloaded and appropriate measures need to be taken to rectify the

situation (e.g. stop the motor or reduce the load).

1

|n_act| < p2161

The actual speed value is less than the set

threshold value (p2161).

|n_act| t p2161

0

|n_act| ≥ p2161

The actual speed value is greater than or the same

as the set threshold value (p2161).

BO: r2199.0

2

Note:

The message is parameterized as follows:
p2161 Threshold value

p2150 Hysteresis
Application:

To protect the mechanics, the gear stages are not switched mechanically until the speed is less than the set

threshold value.

1

|n_act| ≤ p2155

The actual speed value is less than or the same as

the set threshold value (p2155).

3

|n_act| v p2155

0

|n_act| > p2155

The actual speed value is greater than the set

threshold value (p2155).

BO: r2197.1
