Functions
Function
Specification
Feedback resolver or
Accuracy 10 Bit, resolution 12 Bit, rpm range +/-22500 rpm, 2 pole, 7Vrms
Feedback incremental encoder
From 500 increments, 5V supply <150mA, rpm range 4096 increments = +/-18500
rpm, over 500 any number of increments up to 4294967295 can be used (e.g. 500,
512, 1000, 1024, etc.). Please note the permissible output frequency of the encoder
used. This is normally around 200 kHz, the given speed can be used to derive the
permissible maximum increment number.
NORD standard: 2048 inc/rpm, 85°C max. 200kHz (6000 rpm); 100°C max. 100 kHz
(3000 rpm)
Protective measures against
Over-temperature of servo controller and motor
Over and under-voltage
Short-circuit, earth fault, overload
Regulation and control
Travelling profile, torque, speed and positioning control – all in a control cycle time of
50µs
Setpoint input analog
+/- 10 V resolution 12Bit
Speed calculation
16 bit
Motor temperature monitoring
KTY84
Control inputs
6 freely programmable inputs, 10-30 V, e.g. for the PLC
+ and - limit switches, enable, reference, motor temperature monitoring
Control outputs
1 relay 30V AC / DC 2A;
6 freely programmable short-circuit proof outputs 24 V / 25mA, e.g. for the PLC
Interfaces
RS 232
RS 485
CAN bus up to 500 kBit/s
Controller efficiency
Ca. 95%
Interface
Stepper motor interface 5 MHz (cannot be combined with SSI option regarding
hardware, software cannot operate second incremental encoder simultaneously, but
switching is possible with NORD SERV!)
Second incremental encoder input 5 MHz, < 150 mA
Required for gear functions (cannot be operated simultaneously with stepper motor
interface through software, however switching is possible with NORD SERV!)
Ambient temperature
0°C ... +40°C continuous operation
Storage and transport temperature
-40°C ... +70°C
Protection class
IP20
Electrical isolation
Control terminals (digital and analog inputs)
