7.2.2.1 wDriveControl control word
In the control mode "40: Network (MCI/CAN)", the controller is controlled by a master control (e.g.
IPC) via the wDriveControl control word.
• The process data word received from the master control is provided to the application via the
upstream port block LP_Network_In at the wDriveControl input.
• Display parameter: C00136/1
• The bit assignment of the control word can be obtained from the following table:
Motor control
bHeatSinkWarning
BOOL
TRUE Heatsink overtemperature detected
bOVDetected
BOOL
TRUE Overvoltage detected
bDcBrakeOn
BOOL
TRUE DC-injection braking active
bFlyingSyncActive
BOOL
TRUE Flying restart function is executed
nMotorFreqAct_a
C00058 | INT
Current field frequency
• Scaling: 16384 ≡ 327.68 Hz (24000 ≡ 480.00 Hz)
nOutputSpeedCtrl_a
INT
Speed or slip controller output
• Scaling: 16384 ≡ 100 % reference speed ( C00011 )
nMotorSpeedAct_a
C00051 | INT
Actual speed value
• Scaling: 16384 ≡ 100 % reference speed ( C00011 )
nMotorVoltage_a
INT
Current motor voltage/inverter output voltage
• Scaling: 16384 ≡ 1000 V
nDCVoltage_a
INT
Actual DC-bus voltage
• Scaling: 16384 ≡ 1000 V
nMotorCurrent_a
INT
Current motor current
• Scaling: 16384 ≡ 100 % I
max_mot
( C00022 )
nMotorTorqueAct_a
C00056/2 | INT
Actual torque
• With "VFC (+encoder)" motor control, this value is determined from the current
motor current and corresponds to the actual torque only by approximation.
• Scaling: 16384 ≡ 100 % M
max
( C00057 )
nHeatsinktemperature_a
INT
Heatsink temperature
• Scaling: 0 ... 16384 ≡ 0 ... 80 °C
• At sub-zero temperatures, the value "0" is output.
Holding brake control
• For a detailed function description see chapter entitled " Holding brake control ".
bBrkReleaseOut
BOOL
Trigger signal for the motec-internal power output (terminals BR1 and BR2) for
triggering the brake.
• Use bit 0 in C02582 to activate inverted triggering of the power output.
 Functional settings
FALSE Apply brake.
TRUE Release brake.
bBrkReleased
BOOL
"Brake released" status signal considering the brake release time
• When the holding brake is triggered to close, bBrkReleased is immediately set to
FALSE even if the brake closing time has not yet elapsed!
TRUE Brake released (after the brake release time has expired).
