Default:
◼ When CDHD2S is enabled, the brake output is on.
◼ When CDHD2S is disabled, the brake output is off.
2. Go to the Emergency Shutdown screen and set the Active Disable Time (DISTIME). For
example, set the value to 30ms.
3. DISTIME defines the time period after the motor falls below the "Active Disable Velocity
Threshold" (DISSPEED) until the drive is disabled via the "Active Disable" function.
Figure 6-43 Active disable time (DISTIME)
When the "Disable" command is executed, the CDHD2S immediately changes the brake output
value and disables the CDHD2S control after waiting for the Active Disable Time (DISTIME) to end.
When a fault such as STO or loss of feedback occurs, the drive immediately switches the brake
output value and disables CDHD2S control.
6.16 Motor temperature sensor
CDHD2S supports two types of motor temperature sensors: thermostat (on/off) and thermistor
(thermistor).
The following parameters are use to define the motor temperature sensor type and the
response of the drive to over-temperature condition.
Define how the drive responds to motor over-temperature fault. If the
motor has no temperature sensor, or if the sensor is not wired, set
THERMODE=3, and the drive will ignore the fault.
Indicate whether the sensor is PTC (positive temperature coefficient) or
NTC (negative temperature coefficient) type sensor. When using a
thermostat (on/off motor temperature sensor), set THERMTYPE=0 to
define PTC type.
