The servo amplifier controls the motor with a variable frequency 3-phase
sequence. The motor holding brake is also controlled.
The rated voltage U of the motors must comply with the following

N
value:
≥ U ⋅ 0.707
U
N ZK
U : Intermediate circuit voltage
ICV
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-

ry.
The servo amplifier can activate a motor holding brake (24 VDC, max.
1.5 A) directly. The motor holding brake is supplied by the control ele-
ment's supply voltage. Ensure that the power supply is adequately sized
(see "Technical details").
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.
