9. CAN Communication
9.1. CAN Communication
The CAN communication profile in the Optidrive E3 is implemented according to the specification DS301 version 4.02 of CAN in
automation (www.can-cia.de). Specific device profiles such as DS402 are not supported.
The CAN communication function is enabled by default after power up. However in order to use any control functions through CAN,
the following setting is required: P-12 = 7 or 8.
The CAN communication baud rate can be set by using parameter P-36 (Index 2). Available baud rates are: 125kbps, 250kbps,
500kbps, 1Mbps. (with default setting as 500kbps).
The Node ID is set up through drive address parameter P-36 (Index 1) with the default value of 1.
The tables below show the Index and Sub Index required to address each parameter. All User Adjustable parameters are accessible
by CAN, except those that would directly affect the communications.
All parameter values can be read from the drive and written to, depending on the operating mode of the drive – some parameters
may not be changed whilst the drive is enabled
Optidrive E3 provides the following default COB-ID and functions:
Type
NMT
Sync
Emergency
PDO1 (TX)
PDO1 (RX)
PDO2 (TX)
PDO2 (RX)
SDO (TX)
SDO (RX)
Error Control
NOTE
The Optidrive E3 SDO channel only supports expedited transmission.
T he Optidrive E3 can only support up to 2 Process Data Objects (PDO). All PDOs are pre-mapped; however PDO2 is disabled
by default. The table below gives the default PDO mapping information.
C ustomer configuration (mapping) will NOT be saved during power down. This means that the CANopen configuration will
restore to its default condition each time the drive is powered up.

Questions and answers
Hi, problem with max speed p-01 50.0 p-02 0.0 p-03 5.0 only reaching 25.0 max speed 230v input 178v between phases output **** and cabling replaced many thanks
The Optidrive E3 may be limited to a maximum speed of 25.0 due to one or more of the following reasons:
1. Speed Reference Input (P00-03) – The speed reference input might be lower than expected, causing the drive to operate at a reduced speed.
2. Current Limit Reduction – If the overload accumulator reaches 90%, the output current limit is reduced to 100% of P-08, which could restrict the speed.
3. Analog Input Scaling – If an analog input is used for speed control, its scaling or signal level might be affecting the speed.
4. Alternative Ramp Time (P-24) – If P-24 is set and conditions apply, it could be affecting acceleration and deceleration speeds.
5. Derating at High Altitude or Temperature – If the drive is operating above 1000m or in high ambient temperatures, it may be derated, limiting performance.
Checking these factors and adjusting settings accordingly should help resolve the speed limitation.
