3 Description
3.2 Drive controller
The servo motors must be operated in conjunction with a servo amplifier with speed,
torque or position control, e.g. PMCtendo DD4, PMCtendo DD5 or PMCprotego D.
Servo motors, cables and servo amplifiers should always be regarded as one cohesive
system. The most important selection criteria are:
•
Constant standstill torque M
0
[Nm]
• Constant standstill current I
0 eff
[A]
• Rated speed n
N
[min -1 ]
• Mass moment of inertia of motor and load J [kgcm 2 ]
• Effective torque (calculated) M
eff
[Nm]
• Regenerative energy in braking mode
• Overload capacity
• EMC
When selecting the servo amplifier, please consider both the static and the dynamic load
(acceleration/ braking).
3.3 Feedback
PMCtendo SZ motors may be fitted with the following feedback systems:
•
Single-turn EnDat ® 2.2 ECI1118-G2 inductive,
• Multi-turn EnDat ® 2.2 EQN1135 optical.
Single-turn feedback systems provide an absolute position within one revolution while
multi-turn feedback systems specify an absolute position over a number of revolutions.
3.4 Dynamic performance
The PMCtendo SZ motors are designed as standard for applications with high dynamic
performance, i.e. they have the lowest possible mass moment of inertia. As an option the
servo motors can be supplied with an increased mass moment of inertia in order to opti-
mize the inertia ratio between motor and load.
3.5 Operating mode
The servo motors are designed for continuous operation. This corresponds to operating
mode S1 (in accordance with DIN EN 60 034-1).
