A programmable logic controller is a digital computer used for automation
of electromechanical processes, such as control of machinery on factor as-
sembly lines.
Protected extra low voltage is an electricity supply voltage in a range which
carries a low risk of dangerous electrical shock.
The name PLCopen is a registered trademark and, together with the PLCop-
en logos, is owned by the association PLCopen. PLCopen is a vendor- and
product-independent worldwide association, that defines a standard for in-
dustrial control programming.
Program organization unit. This can be a program, function block, or func-
tion.
Power Supply Module.
Pulse width modulation.
Residual current circuit breaker.
A feedback device for servomotors, typically with 2 analog tracks (sine and
cosine).
A servo drive safety circuit that switches off the voltages of the driver com-
ponents for the IGBTs.
Scope is part of the DDS Toolbox software and is used for diagnosis. It ena-
bles internal signals to be depicted.
Servo Drive Module.
Safety Integrated Level II.
Describes an absolute encoder, in which the absolute position for 1 revolu-
tion remains known.
Synchronous serial interface.
Power is on, there is no error in the axis, and there are no motion com-
mands active on the axis.
Safe Torque Off function. On activation of STO, the ISD 510 servo drive is no
longer able to produce torque in the motor.
This term includes the Power Supply Module (PSM 510), the Decentral Ac-
cess Module (DAM 510), and the optional Auxiliary Capacitors Module
(ACM 510).
