E.dOH function
This parameter can be used to select what type of current check is performed.
Additionally it determines whether or not the brake on/off message is displayed. In the
event there is a problem getting a consistently positive phase check, it is possible to
switch to only a magnetizing current check. The possibilities are de ned below.
Value Function
0 Off (for temporary adjustment only)
1 Magnetization current check with brake on/off display
2 Magnetization current check without brake on/off display
3
(default) Phase current check with brake on/off display
4 Phase current check without brake on/off display

Analog input
noise clamp
This parameter can be used to suppress noise on the analog speed pattern. When
adjusted to a value greater than zero it will act as a hysteresis level above which the
analog signal must rise before the drive begins to act on it. With a negative value
the drive applies the same hysteresis to constant speed, i.e. at high speed.
Unit: 0.1 % = 10mV
Value range: 0.1...10.0 %
Default setting: 0.1 %
Recommended adjustment: 0.1%
This parameter adjusts the serial watchdog on the HSP5 com. link between
the operator and the drive. If the operator is removed from the drive, the serial
communication stops. If it does not restart before this timer expires the drive will
trigger a fault and stop the operation of the motor.
A setting of 0 or OFF turns off the watchdog allowing operation of the drive
with the operator removed. Note this mode of operation is recommended only
for trouble shooting purposes.
Unit: 0.01 sec
Value range: 0.01...10.00 sec
Default setting: 1.00 sec
Recommended adjustment: 1.00 sec
This parameter can be used to activate the temperature sensor input (T1 and T2)
on the drive. With this input activated, if the resistance between T1 and T2 becomes
greater than 1650 ohms, the drive will trigger an E.dOH error indicating that the
temperature sensor is too hot. Note: there is a 60 second time delay between when
the sensor triggers and when the drive triggers the fault.
Value range: off...on
Default setting: off
