Enabling Analog Commands

For safety reasons, the Analog command mode is disabled by default. To enable the An-

alog mode, use the PC utility and set Analog in Command Priority 2 or 3 (leave Serial as

priority 1). Note that by default, the additional securities are enabled and will prevent the

motor from starting unless the potentiometer is centered, or if the voltage is below 0.25V

or above 4.75V. Figure 9 shows suggested assignment of Pot 1 to ANA1 and Pot 2 to

ANA4. Use the PC utility to enable and assign analog inputs.

USB communication

Use USB only for conﬁguration, monitoring and troubleshooting. USB is not a reliable

communication method when used in an electrically noisy environment. Further, commu-

nication will not always recover after it is lost without unplugging and replugging the con-

nector, or restarting the controller. RS232 is the preferred communication method when

interfacing with a computer. USB and CAN can operate at the same time on the SBL2360.

Connecting to a computer using USB will not disable the CAN interface.

RS485 Communication

The SBL23xx has a half-duplex RS485 interface. Two signals are present on the 25-pin

DSub connector for connecting to RS485 networks. Connecting these two wires with the

correct polarity is all that is needed to establish a connection. The RS485+ is the positive

signal and RS485- is the inverted signal. Once enabled, the RS485 can be used to commu-

nicate data under the Modbus protocol, or Roboteq’s native serial commands.

Status LEDs and Flashing Patterns

The controller is equipped with three LEDs. A Green Power LED, a Red/Green Status LED,

and a Yellow Communication LED.

After the controller is powered on, the Power LED will tun on, indicating that the controller

is On. The Status LED will be ﬂashing at a two second interval. The ﬂashing patterns and

colors provide operating or exception status infor mation.
