4.4.2.1 PZD1, PZD2
The mapping relation between PZD1, PZD2 and inverter is stable, user can not set the mapping
relation.
(1)
When master transmits the data to slave,
PZD1=STW (control word, mapping to control command word, which address is 0x2000)
Parameters
Address
Parameters Description
（
write only
）
0x2000
Command meaning:
0001: Forward running (no parameters
）
0002: Reverse running
（
no parameters
）
0003: Deceleration stop0004: Free stop
0005: Forward jogging start
0006: Forward jogging stop
0007: Reserved
0008: Run
（
no directions
）
0009: Fault reset
000A: Forward jogging stop
000B: Reverse jogging stop
000C: Wakeup
PZD2 = HSW (frequency setting value, mapping to function code F113, which address is
0x010D)
(2)
When slave sends data to master
PZD1 = ZSW (status word, mapping to drive running status parameters, which address
is0x1005)
Parameters
Address
Parameter Description

0x1005
Drive ratio/inverter status
High-order byte is drive ratio, low-order byte is inverter status
Inverter status:
0X00: Standby mode 0X01: Forward running
0X02: Reverse running 0X04: Over-current (OC)
0X05: DC over-current (OE) 0X06: Input Phase loss (PF1)
0X07: Frequency Over-load (OL1) 0X08: Under-voltage (LU)
0X09: Overheat (OH) 0X0A: Motor overload (OL2)
0X0B: Interference (Err) 0X0C: LL
0X0D: External Malfunction (ESP) 0X0E: Err1 0X0F: Err2
0X10: Err3 0X11: Err4 0X12: OC1 0X13:PF0
0X14: Analog disconnected protection (AErr)
0X19: PID parameters are set incorrectly (Err5)
0X2D: Communication timeout (CE)
0X2E: Speed track fault (FL)
0X31: Watchdog fault (Err6)
PZD2 = HIW (main setting actual value, mapping to output frequency, which address is 0x1000)
