Operating Instructions
Description
24 V (+1, –3 V) power supply
Max. load:
®
VLT
AutomationDrive FC 301: 130 mA
®
VLT
AutomationDrive FC 302: 200 mA
Reference position index number bit 0 (least significant bit). Not used in
fieldbus mode.
Reference position index number bit 1. Not used in fieldbus mode.
Ground for 24 V – common with 39, 55, X55/4, X56/4, and X58/2
To enable operation, this input must be maintained at high in both
digital control mode and fieldbus control mode.
Digital control mode: Errors are cleared on the rising edge. Must be 0 V
for at least 1 ms to guarantee edge detection.
Reference position index number bit 4 (most significant bit). Not used in
fieldbus mode. Not available in VLT
Reference position index number bit 3. Not used in fieldbus mode.
Reference position index number bit 2. Not used in fieldbus mode.
Safe input. Used for STO.
Common terminal for Relay 01.
Normal Open Relay 01 is open (brake activated) during power off and
start-up of the FC 300. It is always open after a Quick Stop procedure or
with an error situation. Relay 01 only closes with motion procedures or if
specified in parameter 19-09 Automatic Brake Control.
Normal Closed
Common terminal for Relay 02.
Normal Closed Relay 02 is closed to indicate an activated electrome-
chanical brake. It is open to indicate a deactivated electromechanical
brake. Not used in fieldbus control mode.
Normal Open
Ground for analog output. Common with 20 and 55.
This analog output delivers either 0 mA (not locked in) or 20 mA (locked
in) at a maximum of 500 Ω.
Power supply for manual JOG inputs (terminal 53 and 54).
Maximum 15 mA.
When high (above 5 V), the drive travels with jogging speed (parameter
19-16) and ramp (parameter 19-17) in the positive direction. When low
(below 5 V), the drive ramps down and stops if no other motion
procedure is activated. Jog positive has higher priority than jog negative.
Not used in fieldbus mode by default. Can be enabled via parameter
19-31 Digital Jog in field Bus mode.
When high (above 5 V), the drive travels with jogging speed (parameter
19-16) and ramp (parameter 19-17) in the negative direction. When low
(below 5 V), the drive ramps down and stops if no other motion
procedure is activated. Not used in fieldbus mode by default. Can be
enabled via parameter 19-31 Digital Jog in field Bus mode.
Ground for analogue inputs. Common with 20 and 39.
Integrated RC-filter for cable screen. Only for connecting the screen
when experiencing EMC problems.
A control card switch is provided for termination resistance.
