Profidrive - Standard Telegram; Overview; Control Word (Ctw) - Danfoss iC7 Series Application Manual

Application Guide | iC7 Series Industry
To ensure sufficient saliency levels under all load conditions, more advanced settings can be set with these 3 parameters:
4.3.3.12 HF Inject Angle Comp Gain (4): Load-dependent offset to the estimated rotor angle.
l
4.3.3.13 HF Inject Angle Comp Offset (5): Offset to the estimated rotor angle.
l
4.3.3.15 IdIq Reference Ratio Pct (7): Disables the existing magnetization current controlling scheme, like MTPA, and introduces a
l
magnetization current as a percentage of the torque current. This parameter can be used to force the motor to run with elevated
magnetization current levels, if it is required to ensure sufficient saliency levels.
These 3 parameters require detailed information about the motor flux at various operating conditions.

Description
1: On.
0: Off.
1: No coast stop.
0: Coast stop.
1: No quick stop.
0: Quick stop.
1: Enable operation.
0: Disable operation.
1: Enable ramp generator (RFG).
0: Reset ramp generator. Output of the RFG is set to 0. The drive deceler-
ates along the current limit or along the voltage limit of the DC link.
1: Unfreeze ramp generator.
0: Freeze ramp generator. Freezes the present output frequency (in Hz).
1: Enable setpoint.
0: Disable setpoint.
0 ⇒ 1: Acknowledge faults.
Acknowledging is edge-triggered, when changing from logic 0 to logic
1.
0: No function.
1: Jog 1 on.
0: Jog 1 off.
Operation is enabled, drive is at standstill, and STW1 bit 4, 5, 6: 0. The
drive runs up along the ramp to jogging setpoint 1.
