Control
Connections
Refer to the Installation Diagram
•
Control wiring must have a minimum cross-section area of 0.75mm
2
(18AWG)
•
Use screened control cables to comply with EMC requirements
Current Limit
(fixed)
A6
B3
Connection to allow the MAIN CURR. LIMIT parameter to adjust the current limit.
Program Stop/
Coast Stop
B8
B9
C9
Removing B8 from C9 (24V) causes a Program Stop (regenerative drive only)
Removing B9 from C9 (24V) causes a Coast Stop
The Emergency Stop relay (normally-open, delay on de-energisation) is not sequenced
via the drive. It is a separate control feature.
Enable
C5
C9
The contact between terminals C5 (ENABLE) and C9 must be closed for the drive to run.
Speed Demand
(Uni-directional)
A1
A4
B3
The 10K potentiometer adjusts the speed setpoint:
Zero speed = Terminal A1, 0V input
Maximum forward speed (+100%) = Terminal B3, 10V input
0
+100
Start/Run
C3
C9
When C3 (START/RUN) is connected to C9 the drive can run provided that:
B8 & B9 are TRUE (+24V)
C5 "Enable" is ON (+24V)

Thermistor
C1
C2
Connect double insulated motor thermal switch or thermistor to C1, C2. The drive will trip
when the thermal switch opens, or when the thermistor resistance exceeds 4k
Ω
maximum (PTC Type A : IEC 34-11 Part 2). If the motor does not have a protective
device (thermistor), link these terminals.
The thermistor input C2 must be connected for the drive to run.
Clean Earth
A1
Via the clean earth rail which originates directly from the main incoming earth rail.
