Motor connection 4- ][Funktion_Motoranschluss
The servo amplifier controls the motor with a variable frequency 3-phase
sequence. The motor holding brake is also controlled.

 Thermal switches and motor feedback systems on the servo motor
are evaluated.
 In the commissioning software PDrive it is possible to select from a
database the appropriate data record and parameters to suit the mo-
tor.
 Motor cables are available ready-assembled from Pilz as an accesso-

Motor holding brake 4- ][Funktion_Motorhaltebremse_protego_D_48_72
The servo amplifier can activate a motor holding brake (24 VDC, max. 3
A) directly. The supply voltage for the motor holding brake is available at
terminals X9B.

DANGER!
Risk from non-safety-related activation of the motor holding
brake!
Activation of a holding brake via output BR+/BR- of the servo
amplifier is not safety-related. Depending on the application,
hazardous motor movements may cause serious injury or death.
A motor holding brake activated by the servo amplifier alone is
not suitable for personal protection.
Block the drive through an additional mechanical holding brake,
which is activated safely (e.g. with the safety card PMCprotego
S1).
