English term or phrase: crowd drive
This fault is calculated based on the difference in measured speed between the crowd drive and the crowd resolver interface

This fault is calculated based on the difference in measured speed between the crowd drive and the crowd resolver interface. If the measured speed difference rises above a preset level a warning will occur. The drive measures the speed of the motor, while the resolver attached to the second reduction shaft measures the load speed.

Note:
If this drive is intended to back up the DC link regeneratively, then the fault response must be parameterized for
NONE, OFF1 or OFF3. so that the drive can continue to operate even after the infeed fails.

acionamento / "drive" de escavação
Explanation:
My best educated guess:

O vídeo abaixo indicado (min. 1:02) se refere a "state-of-the-art AC Drive System". Interpreto AC como "alternating current" (corrente alternada) ou "adaptive control" (controle adaptativo).

Na altura do min. 5:06, ele se refere a "crowd thrust", que provavelmente deve ser o "impulso de escavar". Preste atenção em sua linguagem corporal!

Considerando que "crowd" é o ato de escavar e "drive" é o mesmo que acionamento, temos:

crowd drive: acionamento de escavação

Penso que o contexto se refere ao acionamento de uma escavadeira elétrica para mineração, conhecida em inglês pela abreviação EMS (electric mining shovel). Veja introdução ao capítulo 1 do artigo indicado abaixo, onde aparece o seguinte:

"During the dig phase the shovel makes use of three actuators: swing drive, hoist drive and crowd drive."

Explicando as três fases de acionamento:
swing drive: virada (da escavadeira)
hoist drive: elevação da caçamba
crowd drive: escavação do terreno
