pg. 33
Note: All bit variables have two VCL parameter names. e rst is the name of the bit, and the second
is the name of the byte containing the bit. e bit position within the byte is indicated in brackets
aer the byte name.
Examples:
BIT NAME: Metric_Units
BYTE NAME: OptionBits3 [Bit 5]
BIT NAME: Encoder_Fault_Detection_Enable
BYTE NAME: Encoder_Fault_Detection_Enable_Bit0 [Bit 0]
In the second example, “_Bit0” is part of the byte name, and does not indicate the bit position; this
byte, like all bytes, has 8 available bits.
Within the menu charts, each pair of bit variable names is shown as a grouped set, with the bit name
appearing rst and then the byte name:
Metric Units On/Off
|Metric_Units On/Off
|OptionBits3 [Bit 5]
SDO Write Message
To retain parameter values changed via CANopen SDO write messages following a key-cycle, write a
non-zero value to CAN_EE_Writes_Enabled (object index 0x332F, subindex 0x00) before changing
parameter values. is will cause changes to be written to non-volatile memory immediately. Aer
completing the changes, write the value zero to CAN_EE_Writes_Enabled.
Do not leave CAN_EE_Writes_Enabled at a non-zero value during normal operation, because
damage to the controller’s EEPROM may occur.
CAUTION
Individual parameters are presented as follows in the menu charts:
Motor Technology 0 – 1 Set this parameter to the type of motor in the vehicle:
0 = ACIM (induction motor)
1 = PMAC (permanent magnet synchronous motor)1
Note: A Parameter Mismatch Fault will result unless the
Feedback Type matches the Motor Technology setting:
If Motor Technology = 0 (ACIM), then the Feedback Type
must = 1 (quadrature encoder).
If Motor Technology = 1 (PMAC), then the Feedback Type
must = 2 (sin/cos device).
Motor_Technology 0 – 1
