6.2 Interfaces
[X2.1/2]: Shaft encoder
The connection of the shaft encoder via the 15-pin D-sub plug to [X2] is roughly shown
schematically in the illustration
219H
Fig. 6.4.
The motor controller must first be wired completely. Only then can the operating voltages
be activated for the input voltage supply and the control section. If the polarity of the
operating voltage connections is reversed, or if the operating voltage is too high or the
operating voltage and motor connections are incorrectly connected, the CMMD-AS motor
controller will be damaged.
[X6.1/2]: Motor connection
The motor is connected to the involved terminals U, V and W.
The motor temperature sensor (PTC, SI sensor or N/C contact) is connected to the +MTdig
and –MTdig terminals. (KTY81 ... KTY84 can be used as analogue temperature sensors.
Not in the FCT and not with EMMS-AS motors.)
The motor brake is connected to the terminals Br+ and Br–.
The motors' protective earth conductor is connected to PE of the [X6] plug.
The motor shield is connected to the housing of the CMMD-AS using the screened
connection.
[X9]: Voltage supply
The interface [X9] is present only once on the CMMD-AS.
For operation of the motor controller CMMD-AS, the input voltage supply is connected
to the plug [X9] at L1 (pin 1) and N (pin 2). The PE is connected to Pin 5. In the CMMD-AS
plug-in, the low-voltage monitoring must be adapted to the input voltage supply.
For the control section, a 24 V voltage source is needed, which is attached to the +24 V
and 0 V terminals of the [X9] plug.
An external brake resistance is connected to the contacts ZK+ and BR-CH.
