Cycle diagram for lifting operation

t₁

Inverter enable

t₁ - t₂

The motor runs up to brake release speed
(fixed setpoint speed 7).

t₂

Brake release speed is reached.

t₂ - t₃

Torque threshold P4-15 verified. The inverter indicates a fault if the torque threshold exceeds the timeout set in P4-16.

t₃

Relay opens.

t₃ - t₄

Brake opens within brake release time P4-13.

t₄

Brake is released. The drive runs up to the setpoint speed.

t₄ - t₅

Normal operation

t₅

Inverter lock

t₅ - t₆

Drive slows down to brake application speed
(fixed setpoint speed 8).

t₆

Relay closes.

t₆ - t₇

Brake applied within brake application time P4-14.

t₇

Brake is closed and drive stopped.
