After  starting  the  compressor,  the  drive  observes  the  temperature  from  the  DLT  sensor.  The 
observable temperature range is between -40 and 155°C. 

3.4.8  STO input 

An STO input (

S

afety 

T

orque 

O

ff) is available between terminals 3 and 4 to connect a safety high-

pressure limiter. The input is designed as a protected electronic circuit (PEC) based on the safety 
standard  EN  60335-1.  In  case  of  a  high-pressure  situation  the  drive  will  let  the  compressor  stop 
immediately. The drive will remain in a safe state until the controller sends a clear fault command to 
the drive. 

NOTE: It is not allowed to use any other external power supply with a higher voltage rating to 
avoid damaging the STO input! 

High-pressure limiter specifications: 

▪

  Type: 

Safety switch (NC, ie, normally closed; based on latest version of EN 12263) 

▪

  Contacts: 

Golden plated contacts 

▪

  Powered by:  Internal 24 VDC (terminal 4) 

▪

  Current flow:  Typically ~10mA

 

▪

  Reference: 

Emerson PS4 series 

Caution:  Connect  the  safety  limiter  directly  to  terminals  6  and  7  without  any  relay  etc.  in 
between. Otherwise the safety will probably not be guaranteed any longer. 

3.4.9  Modbus communication 

The drive acts as a Modbus slave with a pre-selected address 45. The serial communication between 
drive and any kind of controller or user interface is physically driven via RS485 (control terminals 5, 
6 and 7) and logically via the Modbus

®

 RTU protocol. If a master controller needs to be supplied with 

5 VDC the control terminal 8 can be used. 

During start-up cycle, if the auto-adaptive function is enabled, the drive can automatically detect the 
baud rate and parity. If communication auto-adaptive function is not enabled, the drive will use baud 
rate and parity read from EEPROM. Further information is provided in the Modbus

®

 Map. 

3.4.10  Drive cooling control 

The  drive  provides  temperature  values  from  the  power  modules  mounted  on  the  heatsink.  These 
values should be used to monitor and control proper drive cooling from system side. 

Dedicated registers for temperature sensing: 

▪

  [70]: PIM Temperature 

▪

  [22]: PIM Overtemperature 

▪

  [42]: PIM Speed-drop protection limit 

Exceeding  the  overtemperature  limit  (register  [22])  the  drive  will  immediately  shut  down  the 
compressor. When the temperature of the power module reaches 80°C (stored in register [42]), the 
fan  starts  close  to  full-speed  and  then  gradually  reduces  its  speed,  while  the  temperature  of  the 
module decreases. The fan will stop only if the drive is turned off.
