Drive control board (CB) temperature.
0150 CB TEMP
Temperature of the drive control board in degrees Celsius/Fahrenheit.
Note: Some drives have a control board (OMIO) that does not support this feature. These drives always show the
constant value of 25.0 ºC.
3024 CB TEMP FAULT
Defines the drive response to control board overheating.
0 = – No response

8128 AUX START ORDER
Sets the start order of the auxiliary motors.
1 = – Time sharing is active. The start order depends on the run times.
EVEN RUNTIME
2 = – The start order is fixed to be the order of the relays.

2112 ZERO SPEED DELAY
Defines the delay for the Zero Speed Delay function. If parameter value is set to zero, Zero Speed Delay function is
disabled.
The function is useful in applications where a smooth and quick restarting is essential. During the delay the drive
knows accurately the rotor position.
Speed
Zero speed delay can be used e.g. with jogging function or mechanical brake.
No Zero Speed Delay
The drive receives a stop command and decelerates along a ramp. When the motor actual speed falls below an
internal limit (called Zero Speed), the speed controller is switched off. The drive modulation is stopped and the motor
coasts to standstill.
With Zero Speed Delay
The drive receives a stop command and decelerates along a ramp. When the actual motor speed falls below an
internal limit (called Zero Speed), the zero speed delay function activates. During the delay the functions keeps the
speed controller live: The drive modulates, motor is magnetized and drive is ready for a quick restart.
2113 START DELAY
Defines the Start delay. After the conditions for start have been fulfilled, the drive waits until the delay has elapsed
and then starts the motor. Start delay can be used with all start modes.
• If = zero, the delay is disabled.
