11.6.1Introduction

If the power fails, a drive line-up normally responds with OFF2 even when a Control Supply Module is used in conjunction with a Braking Module (i.e. the connected motors coast down). The Control Supply Module provides the electronics with power via the supply system or DC link. In this way, controlled movements can be made if a power failure occurs, for example, provided that the DC link voltage is available. The following section describes how all the drives carry out an emergency stop (OFF3) if the power fails.
